July 4th Update

Hello all,

Celebrate July 4th, 2020 at GunColony and our Discord server! We have added a new Gas Station map, a new weapon, and tons of weapon remodels. Also enjoy much better server performance, new donor perks, and the ability to unlock PVP early by linking your Minecraft account with Discord.


We have adopted a new Discord linking system to link your Minecraft account to Discord. You can do this fully in game!

  • Method 1: in-game type /discord link. This will give you a code and instructions to link your account in Discord.
  • Method 2: in Discord, message “GunColony Chat Bot” with !link <MinecraftUsername>, then follow the instructions. The bot should be at the top of the user list in discord.

You will now earn in-game rewards when linking your Discord account.

  • Instantly unlock Versus (usually level 8)
  • Instantly unlock PVP (usually level 15)
    • If you are below level 8 and still in the newbie lobby, you need to use the “Join A Game!” sword to join VS or PVP.
  • Unlock the exclusive RPK-12

This makes it possible players to get into a PVP match if they really want to, while keeping it difficult enough so that low-skilled newbies and cheaters are less likely to figure out how to join a PVP match.


RPK-12: A prototype AK-12 with a long barrel and bipod for use as a LMG. It has similar stats to the QBB-95; worse firepower and magazine capacity, but better handling and has a special three-round burst mode with a fast fire rate. The RPK-12 is exclusively awarded for linking your Minecraft account with Discord.


We have added new models to 20 existing weapons, six of which are for machine guns! Gunning down hordes of enemies with a LMG has never felt this satisfying.

  • SC-2010
  • RFB
  • M1918 BAR
  • QBB-95
  • M249
  • Negev
  • Lewis Gun
  • M1915 CSRG
  • M3
  • Remington 887
  • Mosin-Nagant
  • Gewehr 98
  • M3 Grease Gun
  • MP5
  • MP5SD
  • MP5K A4
  • USP-S
  • Mauser C-96
  • P2000


Gas Station: Help defend the gas station to prevent our oil reserves from being destroyed by the zombies! This map is relatively easy in difficulty and unlocked at Level 4.

Bonus: As a July 4th special, Deserted is available to all players regardless of level for a limited time!


We have added another way to unlock modes early by buying a rank on our donation store.

  • Recon rank will instantly unlock Versus, PVP, and Competitive
  • Specialist rank will additionally unlock all Mob-Arena maps


We have done some targeted optimizations to GUIs and data management (particularly around storage access) to reduce lag spikes and speed up general performance.

  • Switched the two most problematic read-only GUIs (/gun and the PVP Shop) to run async
  • Inventory saving to MySQL is now run async except for when the server is stopping (serialization is still synchronous)
  • MobArena class chest contents will now be cached instead of querying the chest (usually in an unloaded chunk) every time the player is spawned
  • Guns and particles will now properly avoid checking block collisions in unloaded chunks, which should greatly speed up performance in wide open maps where bullets fly outside the map freely
  • Level 0 players no longer store a permission group to save space on the permission groups database and reduce lag when a player joins for the first time
  • Tweaked JVM settings to reduce lag spikes from garbage collection

Generally speaking, the only remaining lag problems now are when players join or teleport around (especially on 1.13+), and when there are simply too many players on the server to process at once. We are working on a multi-server network system that will fix these problems in the near future.


  • Reduced movement speed of the cave spider spawned by the Steed boss skill
  • Greatly reduced the unlock level of Mob-Arena maps (almost all maps now unlock before Level 40)
    • New Mob-Arena challenges for high-level players will be coming in the future


  • Fixed a bug where level 0 players could not rankup
  • Fixed a bug where the FAMAS had incorrectly low spread when hip firing in burst mode
  • Some security improvements like disabling the automatic firewall rules module in the new server panel

Signal Update

Hello all,

This minor update adds 1.16 client support and new themed content. Use mortar strikes and air support against mobs and defend the signal tower to keep communication with HQ. Enjoy less lag when staff are building on the build server.



Signal Hill is a new MA map with a unique spawning mechanic different from all other maps in the game. Hordes of monsters will spawn far away and slowly climb up the hill to get to the players. It is unlocked at Level 8 as soon as you leave the newbie spawn.



We have added two airstrikes that drop rarely within MobArena.

Mortar Strike: Calls in powerful mortar shells that drop in a medium area. Remember to use it outdoors! There is a significant delay before the shells land.

A-10 Airstrike: Calls in a strafe run that eliminates enemies in a straight line and is able to penetrate soft cover. The direction of the strafe is controlled by the direction you’re facing. The plane is currently not visible but we’re looking into ways to show it in game.

They have currently not been added to PVP but we might consider adding them in the future alongside a more fleshed-out killstreak system.


We have updated ViaVersion to support Minecraft 1.16 and 1.16.1 clients.


  • Moved server to a new admin control panel
  • Moved the staff build server to a new host so it no longer shares CPU and RAM resources with the GunColony server


  • The MobArena Quick Join GUI now has the Quick Join icon prioritized, whereas the Start New Game icon is moved to the top right corner because it is less commonly used
  • The MobArena Quick Join GUI is modified to accommodate for mixed-case maps like SignalHill
  • The Low Player Bonus in MobArena now affects player XP as well as weapon XP
  • The spawn help signs have been simplified and no longer contain duplicate information
  • Moved map NPCs in the newbie spawn to reduce clutter
  • Added some banners to prevent the holograms on the main spawn from showing through to players in the newbie spawn


  • Fixed a glitch where the Join Game sword took you to the MobArena lobby instead of opening the Quick Join GUI
  • Fixed a glitch where a projectile shot stright up/down could cause a NaN when calculating pitch
  • Fixed a glitch where the weapon tracers originated from different positions between the first tick and subsequent ticks, making it appear glitchy especially on slower velocity weapons
  • The knife right click swing animation now works for 1.13 and above clients

MobArena Tactics Update

Hello all,

Today’s update adds weapon knockback and better throwable items to Mob-Arena to make the mode more complex and replayable. Additionally, we have tweaked some of the new features added in the last update to reduce the amount of unlock grinding for new players.



Street is a Mob-Arena map that unlocks at Level 2. It provides a great zombie survival experience to introduce players to GunColony. It features mini-bosses and several custom mobs to provide something interesting and different to new players while also familiarizing them with our custom game mechanics. It has 20 waves on Easy, and 30 waves on Hard.

Overpass is a map inspired by CS:GO. It features a large layout with plenty of medium-range sightlines and some verticality. It is available in TDM Random Spawns and Defusal.

Crossfire is a map from Black Mesa. It has a lot of vertical height and features the interiors of the buildings and bunker. It is available for Free For All.

Ravine is a compact Free For All map. It takes place in a large cave system with buildings hanging from the ceiling. Don’t fall off the walkways!



We have added a new Knockback mechanic inspired by old versions of GunColony! Shooting at monsters will now knock them back. The amount of knockback depends on the damage you deal. If you want to reliably knock back monsters, a Sniper Rifle, Shotgun, or Grenades are your best bet.

Note that bosses can only be knocked back if you are its target (prevents everyone knocking the boss around in large maps).


We have increased the drop rate of items and added new items to the drop pool in Mob-Arena. We have also rebalanced all grenades dropped within MA, giving them different strengths and making them all viable to use inside the game.

  • All grenades: Throw distance have been reduced to allow players to throw them more precisely; damage penetration value has been increased allowing mobs to be damaged through walls, but the amount of damage is still reduced depending on the type of cover.
  • Grenade: Now has lower max damage (480 -> 350) but much larger area of effect. Fuse reduced from 3 to 2 seconds.
  • Impact Grenade: New addition! Detonates on impact, but has much lower damage and effective radius than the Frag Grenade.
  • Stick Grenade: New addition! Has the highest explosive radius and penetration, and can be thrown further than other grenades. Slow swap time and medium damage.
  • Stun Grenade: New addition! Detonates on impact; slows and weakens mobs within a huge radius for 6 seconds. Also deals some damage and knockback.
  • Gas Grenade: New addition! Very rare drop. Gives slowness and deals relatively low damage for a very long duration of 45 seconds. Hard for players to see through it.
  • RPG-7: New addition! Very rare drop. Shoots 3 explosive rockets with similar damage profile as the Impact Grenade.
  • M202 Flash: New addition! Very rare drop. Shoots 4 explosive rockets at a higher fire rate than the RPG-7, but the rockets have less radius.
  • Bandage: Renamed from Healer. Drops more often than before.
  • Health Pack: Drops more often than before.
  • Healer Shot: Regen duration doubled to 20 seconds. Comparatively rarer than other healing items.

Mob-specific drops:

  • Bouncy Slimeball: Now has higher damage overall and a large knockback.
  • Explosive Magma Cream: Now has higher damage overall and a large knockback; does not bounce as much off surfaces so it is easier to aim the explosion.
  • Shulker Bullet: Now shoots 5 bullets instead of 1 to improve its ability to levitate groups of mobs. Levitation now lasts longer. Damage per projectile reduced.
  • Speed Powder: New! Drops from Blazes. When used, it gives Speed III for 45 seconds.
  • Lightning Bolt: New! Drops from Powered Creepers. Shoots a laser beam with extremely high damage that kills an entire line of mobs, and then causes a powerful explosion once it hits a block.


We have reduced the damage of most weapon types in Mob-Arena to balance out the knockback and throwable buffs, and to better balance the different weapon categories.

  • Fully-automatic ARs, SMGs, LMGs: 60% damage; +15% damage when switched to Semi-Auto or Burst
  • Semi-automatic ARs, Snipers, Shotguns: 70% damage
  • Pump-action, Double Barrel Shotguns: 80% damage
  • Handguns: 90% damage
  • Bolt-action Snipers: 100% damage

Special Weapons:

  • Flamethrower, High Voltage Gloves: 60% damage
  • Laser-451, Crossbow, Fire Launcher: 100% damage
  • Knife: left click damage increased 37.5 -> 50, right click stays the same (97.5)


We have re-enabled our Tech Tree system to help you unlock weapons faster! To unlock a weapon with this system, you have to play with a specific prerequisite weapon in-game and level it up. Then, you will get two benefits that help you unlock the weapon:

  • The token purchase price of the weapon will be 60% off
  • You can randomly find and unlock the weapon in crates


We have made improvements to the PVP spawning algorithm to better avoid spawning players near enemies.

  • If an enemy is within 10m of a spawnpoint, it is now ignored completely while choosing spawns
    • If an enemy is within 30m, spawn chance is reduced
  • If an enemy is within 30m and can see the spawnpoint, the spawn is ignored completely
    • If an enemy is within 50m and has line of sight, spawn chance is reduced

These changes affect TDM Random Spawns and FFA mode. Friendlies still increase the chance of nearby spawnpoints just as before.


Newbies have had a hard time reaching the unlock requirements of Versus and PVP modes after the previous update. We have significantly reduced the level requirement of all game modes to allow new players to access them earlier. Note that these changes may be reverted in the future when we introduce Discord linking to unlock PVP and/or another way for new players to level up faster such as newbie quests.

  • Versus unlocks and the main spawn is accessible at Level 8, rather than Level 10
  • PVP unlocks at Level 15, rather than Level 20
    • The experience required to unlock PVP has almost been cut in half as a result of this change
  • Competitive unlocks at Level 25, rather than Level 30


  • You will now respawn in 90 seconds instead of 120 if you die during a boss wave
  • The MobArena Quick Join menu now shows a red “Requires Level x” text if your level is lower than the required level of a map in progress
  • The respawn time message after you die now shows the remaining time in “x minutes, x seconds” format.
  • Decreased the level requirement of several Mob-Arena maps.


  • Fixed a glitch where grenades were inaccurate if switching to one while moving/sprinting
  • Fixed a glitch that caused Free For All spawns to be completely random instead of avoiding other players
  • Fixed a glitch where everyone is put into the beginner spawn after exiting Mob-Arena regardless of their level
