New features

  • Border-less window mode -- enable this with r_borderless 1 (also in advanced options).
  • Extra features for donors and staff is now received on-line, so new donors can enjoy our thank you features much sooner.
    • HTTP connectivity to our game API server is required.
    • If the on-line database is unavailable to the game server the hard-coded list in the server binaries is used instead. Only donors after release will be unable to get their extra features in this situation.
  • Linux server binary -- 100% native!
    • Fixed func_rotating visually stopping after it has rotated beyond 32,767 degrees.
    • Maps will need to have resource file names in the correct case or the Linux server will not find them and crash.
  • New map Quarter: A defensive map with multiple stages.
  • Player spawn points are now selected at random (from those that are active) with no spawn-fragging.

Code changes


  • Added obey trigger mode property to func_train.
  • Added entity alias trigger_create_entity for entity trigger_createentity.
  • Added ignore tiny monsters property to trigger_* entities, to ignore insects, hornets, and other very small monsters activating triggers.
  • All item_ entities use a specific hull size very close to the default model size rather than being too big, (mostly) fixes items disappearing inside walls.
  • Blood splat scale reduced.
  • Cheat commands:
    • All unsuccessful cheat commands are now logged on the server as warnings.
    • If sv_cheats is 2 only server administrators can use cheat commands. Designed for map authors to test their map with others in a controlled way. Players can always check who cheats are available to if they care with the mapinfo command.
    • NEW: healme heals your health to the map defined limit.
    • NEW: chargeme charges your HEV battery to the map defined limit.
    • reviveme can no longer be used if you're alive.
    • NEW: trigger remotely trigger an entity (first parameter is the entity name, second optional parameter passes a numeric value to the entity).
  • Client commands:
    • All commands are now case insensitive.
    • All commands with a repeat delay now share the same reset timer, reset in 4 seconds, and shows the exact time left to 1 decimal point.
    • All commands can be logged on the server by setting CVAR sv_log_client_commands to 1, though this can be quite spammy.
    • grenade and stuck can't be used while the player is a Barnacle victim.
    • grenade now executes npc_findcover automatically, so a dual-bind is not required.
    • mapinfo formatting improved, also shows who can use cheats (off, on, or administrators only).
    • medic now makes a strangle sound instead of a medic call for players that are Barnacle victims.
    • NEW: myinfo displays your target name and model, this will be expanded to show more properties about you in the future.
    • NEW: stuck moves players into free space should they become stuck in a wall or anything else solid (limited to 48 units, alias unstuck).
    • submitid no longer checks for a repeat delay if the player can't use the command anyway.
  • Client will show an error message if the game is NOT using the OpenGL renderer.
  • CVAR mp_telefrag is now writable by maps (configuration and trigger_setcvar).
  • Default maximum velocity increased from 2,000 units/second to 4,096 units/second.
  • Default maximum viewing distance increased from 8,192 units to 32,768 units.
  • Default setting for detail textures is now enabled.
  • Default skill level now 1.
  • Fixed a ton of possible crashes/freezes caused by buffer overflows, memory leaks, and uninitialized memory across the entire game. Oh the joy of many programmers over the years ...
  • Fixed administrator list file requiring a new line after the last entry in the list.
  • Fixed crash during gun fire if players had mp_decals set to 0.
  • Fixed crash if the map voting list exceeded the stack size (moved to heap).
  • Fixed env_blood shooting white particles when red blood was specified.
  • Fixed func_tank eye positions, so it will work properly as the tank rotates.
  • Fixed func_train dealing crush damage every frame.

  • Fixed monster_barnacle having inconsistent tongue lengths when multiple Barnacles grab the same victim.
  • Fixed monster_barnacle not always releasing players during a trigger_respawn.
  • Fixed monster_barnacle possible crash with the prey entity referencing.
  • Fixed monster_barnacle victims rising infinitely if they end up above the Barnacle (often by multiple barnacles grabbing the same victim, or the victim walking on top of a Barnacle).
  • Fixed server lag from players having their donor/staff/administrator levels looked up every time they spawn or use a donor feature.
  • Fixed squadmaker possible crash with the render override.
  • Fixed squadmaker entities with names not starting automatically when the start on flag is defined.
  • Fixed trigger_condition comparing strings with non-strings.
  • Fixed trigger_changevalue not setting hull sizes correctly (passes new size to the engine).

  • Skill configuration will no longer print on map load, unless developer is at least 2.
  • Spawn point handling:

    • Collision detection to prevent spawn-fragging.
    • Only 1 type of spawn point entity will be used, depending on what is active at the time: _deathmatch then _dm2
    • If no _deathmatch or _dm2 spawn point can be used, a _coop or _start point is used.
