Update 1.11: Spooky Seas

Hello all,

Halloween has always been a time of significant Mob-Arena updates, and this year is no different! In this update, we have added Nautilus, a Mob-Arena map set in an underwater base and possibly the most unique map yet, alongside a host of water-related tweaks to the gamemode. This update also brings a seasonal Halloween spawn and PVP map, Spukhaus, as well as two other interesting maps, including the fan-favorite Nostalgia Subway and the beautiful Cyberpunk map!


We have added a new seasonal spawn for the spooky season, built by MontanaMob! Explore the challenging parkour course in this spawn or earn some XP shooting at the pumpkin targets in the shooting range and elsewhere in this spawn.

These block-based targets in the new spawn also have the side benefit of allowing for much better FPS than the previous entity-based targets.

Only players level 8 and above will spawn in this seasonal spawn. New players will still use the newbie area of the normal spawn.


In Nautilus, your job is to defend an underwater base from the undead of the depths! Nautilus is the first GunColony map to fully take advantage of Minecraft’s new(-ish) water mechanics. You can traverse outside the base for temporary safety and relocating to different parts of the map, but beware of your oxygen gauge and the aquatic mobs that may lurk out there!

Nautilus was built by Hotline_101 and features 50 waves on Normal and 52 waves on Expert. The final boss fight on Expert mode is very unique and challenging, but I won’t spoil it!


Happy Halloween! To preempt your trick-or-treating this evening, we are bringing you a new Halloween seasonal map made by MontanaMob. This spooky house has many secrets and a unique layout focused on random spawns modes.


Cyberpunk is a futuristic PVP map built by Mohorowe. While the playable area is relatively small, the map offers a scenic view of the surrounding cyberpunk city, and players can expect a good mix of combat ranges and fast-paced gameplay. Do not fall into the toxic sludge around the map, or you will die!


Nostalgia Subway is a reimagining of the classic Subway map by Hotline_101. It is based on the same classic style and layout as the original Subway map from 2017, but using new blocks and features added to GunColony such as glass shattering. As one of the first original GunColony map layouts, old-timers in the server will certainly find this map to be a nostalgic experience!

  • The Twilight-styled Mob-Arena boss will now wear a cool Dripleaf hat

  • When the player is inside water, damage from Guardians and Elder Guardians is now decreased by 20%
  • Hitting a Guardian will now sometimes interrupt its laser attack
  • Normal Guardians can now only attack players up to 25 blocks away. For Elder Guardians, the distance is 50 blocks.
  • Guardian damage is now decreased the further away the target (decreased by half per 25 blocks)
  • Guardians no longer damage players multiple times in quick succession
  • Endless mode maps in the map list GUI should now reliably show the infinity symbol as the total number of waves
  • Fixed certain instances where mobs spawn inside walls in Mineshaft
  • You can now directly join the Endless Mob-Arena server using the “/server endless” command instead of using the map selector (it will no longer kick you back into the lobby)
  • Pufferfish will now drop both the Pufferfish item and a milk bucket


The staff build system has received some improvements that increases the diversity of maps that will make it into both PVP and Mob-Arena!

  • Added the ability to change the shape of objectives. Previously, all objectives had to be spheres, but now objectives support multiple shapes, including a sphere; cylinder; cube; and World-Edit selections.
  • Added support for gameplay areas such as killzones, and areas that players cannot enter. The gameplay areas can similarly select from multiple shapes. This is used to add a killzone to the toxic sludge in Cyberpunk.


Nautilus, as well as any new Mob-Arena maps going forward, are built on a brand new Mob-Arena map system. The new map system for Mob-Arena brings about a host of improvements:

  • Staff members can now build the map on the StaffBuild server, and the map can be added in-game easily
  • The ability to easily specify mob spawns in-game, rather than a config file
  • The ability to give the same name to multiple mob spawns
  • The ability to set the Minecraft difficulty per-map

Currently, this comes at the cost of needing a few seconds to load a map, causing a short freeze for anyone playing on other arenas in the same server. We will aim to implement optimizations that decrease this performance impact in the future.


  • Changed the name and description of the Musket and Crossbow in the Overpowered Scenario

Update 1.10: October Fools

Hello all,

After the April Fools event earlier this year we promised to come up with something even better. Today we have added a new Overpowered scenario containing many ideas in the original April Fools event, as well as two new maps, an overhaul to the Zombie Siege gamemode and several important bug fixes.


Keep is an indoors map set in a medieval castle, created by James_4007. This map contains a mix of tight spaces and large open corridors that will test your reflexes and allow for a significant weapon variety. It is available in Free-For-All, One in the Chamber, King of the Hill, and Arms Race.


Copper is a map built by Mohorowe and set in a museum exhibit. It is separated into upper and lower floors for two exciting theaters of combat, and the glass roof is destructible allowing air support to be called in. It is available in TDM Random Spawns, Domination, and Defusal.


The new Overpowered scenario contains many goofy and completely not-balanced weapons that will allow you to defeat enemies in one hit, escape the map, rain down explosive fire, or all of the above! It also comes with a special killstreak shop containing Overpowered versions of all four airstrikes in GunColony, as well as the GAU-8 cannon as the ultimate reward! Supply gain in this scenario is based on money gain. Contribute to your team’s effort in order to unlock more powerful weapons in your loadout!

This scenario will be available across many maps in a limited-time playlist, and then return to being available on the few maps, replacing the old Overpowered scenario.


The Zombie Siege mode has received a total rework in this update! We wanted to make it more fun to play as the zombies and the wolves, so we gave them the ability to equip Loadouts similar to the new Scenario Mode. There are also custom Shop items available for both Zombies and Wolves!

Both Zombies and Wolves earn 1 Supply per kill and an additional 1 Supply per $500 earned.

Zombies start with 10 Supply and can equip the following items:

  • Zombie Slime: primary item exclusive to the Alpha Zombie.
  • Zombie Healer: secondary item that allows the zombies to heal but cannot move while doing so.
  • Speed Boost: secondary item that increases movement speed by 20% when held.
  • Tactical Rock: secondary item that can be thrown at humans to deal damage with unlimited ammo.
  • Zombie Leap: secondary item allows the zombie to charge forward or upwards, with a long cooldown.
  • Knockback Grenade: knocks back and slightly damages humans. Yes, it actually works now.
  • Poison Bomb: poisons nearby humans when it explodes.
  • Smoke Grenade: a standard smoke grenade that can be used to block the line of sight of humans.
  • Flashbang: a standard flashbang that can be used to blind humans.
  • Stun Grenade: an expensive grenade that can be used to slow down the humans’ movement speed. Much smaller radius than the version in Mob-Arena.
  • Lightsaber: a very expensive, upgraded melee weapon awarded to the most distinguished zombies by the Lich himself.
  • Perks: a variety of perks relevant to Zombies are available, such as Ninja and Bloodthirst.

Zombies can buy the following items in the Shop:

  • Medishot: an inexpensive item that provides slow, passive regeneration.
  • Health Pack: provides some health and absorption. Somewhat spammable.
  • Medikit: provides 10 hearts of health and absorption.
  • Speed Powder: increases movement speed greatly for 45 seconds. Expensive to purchase.
  • Zombie Bow: a standard Minecraft bow.
  • Zombie Arrow: standard Minecraft arrows.
  • TAG: highlights humans and is cheap to purchase. Can be useful for finding humans who are hiding.
  • Zeus x27: a more potent melee weapon that has only one use.
  • Gas Grenade: an expensive grenade that can force humans out of a position.
  • Golden Gun: a very expensive weapon that can instantly kill a human with good aim and refund its cost back if you eliminate either a human or wolf with it.

Wolves start with 3 Supply and can equip the following items:

  • 4 tiers of Dog Bite melee attacks. Each tier is more expensive but provides an attack rate and movement speed boost and other bonuses.
  • Lightsaber: a very expensive melee weapon for the most dedicated zombie-slaying canines.
  • Hardcore Weapons: a few hardcore guns are available for wolves that have way too many kills under their belt.
  • Speed Boost: a 20% speed boost that is cheaper for wolves than for zombies, but cannot be stacked with the movement bonuses from upgraded melee items.
  • Zombie Leap and Zombie Healer: same as the zombie variants, these evil gadgets have been stolen from the infected by seasoned wolves.
  • Grenades: an assortment of standard grenades are available for wolves.
  • Perks: a variety of perks relevant to Wolves are available, such as Curse and Divine.

Wolves can buy the following items in the Shop:

  • Soup: restores 2 hearts.
  • Speed Powder: provides a temporary speed boost.
  • Airstrikes: all four airstrikes are available. Perhaps a human has trained a wolf to dispatch them at strategic coordinates.
  • M202: a wolf firing rockets. Why not?
  • Golden Knife: provides extra money on kill but is itself expensive to purchase.
  • Quakecraft Gun: become a laser-firing super wolf.
  • Reloadable Mini-Nuke: that’s it, you’ve won the game for your fellow Humans…

Other Zombie Siege changes:

  • Humans now gain Resistance instead of Regeneration for staying near the human spawn
    • This change was made because the human spawn mechanic encouraged camping more than we’d liked
    • Humans should now use the Shop to purchase healing items
  • Zombies now drop ammo on death, helping humans defend against the stronger Zombie threat
    • Humans are encouraged to move around the map more to access ammo drops
    • The Alpha Zombie drops twice as much ammo as other zombies
  • Zombies no longer have armor and helmet by default and must now equip them in their loadout
  • Decreased the price of many single-use items in the human Shop
  • The Alpha Zombie’s slimeball attack now deals significantly more impact damage
  • With less than 2 minutes remaining, the zombies will get an additional Knockback Grenade upon spawning just like before (except it actually works now)
  • Increased the swap speed of Dog Bite
  • Increased the price of RBB-451 in the human Shop from $7500 to $10000


  • Air strikes no longer display the block crack effect when damaging blocks in Mine-Spades
    • This prevents extremely low FPS after an A-10 airstrike or cluster strike is called in during a Mine-Spades match
  • The airstrikes can still damage blocks normally; only the block crack effect was removed


  • The chance of Zombie Siege maps appearing in the map vote has been increased by 3x for a limited time
  • Added a limited-time Overpowered playlist containing a large quantity of Overpowered scenario maps!
  • Removed the GroundWar™ limited-time mode
  • The Halloween “GhostGulag” scenario has been enabled


  • Added the “Flash” particle effect to Flashbangs and Stun Grenades


  • Fixed a bug where if a mob failed to spawn in Mob-Arena due to the monster limit, it would count as not yet spawned, leading to excessively long wave timers during high waves in Endless mode
  • Fixed a bug where Mob-Arena matches that are not ongoing and belonging to completely empty servers can sometimes show “Wave x – 0 Players” or sometimes a different player count, but upon joining would lead to an empty match
  • Fixed a bug where block crack particles by items like the Bandage would display the wrong block

Update 1.8.1: July 4th Map Update

Hello all,

Happy American independence day! Today we have added four new maps, as well as a limited-time playlist. All new maps will also have a 3X higher chance of appearing on the map vote!



Sasau is a sprawling map made by James_4007 and set in a rural town surrounded by farmland. There is an open fighting area in the center, surrounded by flanking routes. Weapons with good wall penetration may be of use to pierce the wooden buildings in this map.

Sasau is available in Team Deathmatch, Kill Confirmed, Free-For-All, Team Deathmatch, and Zombie Siege


Santorini is a map made by CrishTheCreator based on the CS:GO operation map of the same name. The map features tight corridors and is available on TDM, Domination, King of the Hill, Zombie Siege, Elimination, and Defusal.


Nightclub is a tight close-quarters map also by James_4007, with a central objective that is surrounded on all sides by high platforms and balconies. Covering your team members with CQB tactics and fast decisions will be paramount when fighting in the King of the Hill mode. The map is also available on Team Deathmatch, Free-For-All, and Arms Race.


Caspian is a map set in the desert hills, made by Poe13, Ferret95, and FireProdigy_. It is specifically designed for the Elytra mode and is sure to bring about some awesome dogfights!

The map is suitable for a variety of player counts. Both teams spawn on the same side of the map, which results in a smaller layout in the TDM mode. However, the central Hill and bunker will be a huge site of contention in the KOTH mode, and Domination mode will see players additionally fighting for dominance over the two opposite corners of the map. Which team will come out on top depends on your skill and reaction time as an Elytra pilot! The map is also available on the FFA mode for some pure chaos in the sky.


We have brought back the GroundWar™ mode as a limited-time playlist! This mode gives players overpowered killstreaks on each kill so that you can enjoy the July 4th fireworks in Minecraft!

The mode is available on all of the new maps as well as Sakura. A Mine-Spades version is available on certain maps for maximal map destruction.

Maps with this event will appear with 1.5X chance in the map vote (half the chance of the normal playlists for the new maps).


  • Resistance has been removed (again?) from TDM and FFA
  • Sakura has been added to Arms Race as the largest map in the mode’s playlist
  • Sakura has been added to TDM Random Spawns
  • 5xShipment has been added to the Elytra mode
