Alien Swarm Patch Notes – February 10, 2022

General

  • Fixed several rare crashes.
  • Cleaned up memory leaks.
  • Improved performance by removing unnecessary calculations throughout the codebase.
  • Disabled some spammy developer warnings by default.

Aliens

  • Fixed Buzzer poison getting stuck if a player died while it was active and did not switch to another marine.
  • Fixed Parasites and Xenomites being immune to blast damage when fully submerged in water.
  • Killing a large number of aliens at once no longer crashes the game in some rare cases.
  • The death animation of Shieldbugs no longer causes rare client crashes.
  • Fixed Drones getting stuck when dismounting info_node_climb.
  • Fixed a case where Drones would navigate to the wrong location when pathfinding failed.
  • Parasites should no longer appear to be growing outside of their egg or spawn at the wrong place when jumping out of an egg with unusual angles.
  • Mortarbug shells no longer block moving platforms.
  • Buzzers properly enter and exit the sleep state when far from players.
  • Drones will no longer “warp” past marines on challenges with very high drone acceleration.
  • Aliens with moveclone set do not trigger physics collision code. This improves performance on maps like Cargo Elevator that use aliens in a cinematic way.

Weapons

  • Extremely short range shots will no longer cause incorrect decals or impact animations.
  • X33 Damage Amplifier and IAF Heal Beacon bounce in place or fall through the floor when placed on a moving platform.
  • M478 Proximity Incendiary Mines no longer fall through certain types of dynamic floor.
  • ML30 Laser Trip Mines no longer explode when touched by an invisible character.
  • SM75 Combat Flares and TG-05 Gas Grenades no longer collide with NPC Clip.
  • Fixed an issue where grenades would aim incorrectly if the marine had been hit from behind very recently.
  • Fixed collision inconsistencies between mines and various types of throwables.
  • The beam of the mining laser no longer gets stuck if the weapon is deleted by a script.

Misc

  • Fixed doors getting stuck with negative health if they were killed from the side they were dented towards. Extremely high damage can correctly knock down a door in one hit.
  • Sentry bases now use a different skin number for each type of sentry.
  • Improved the performance of rm_welcome_message.
  • Made the cheat convar asw_unlock_all_weapons available outside of debug builds.
  • Added asw_create_generic_emitters_for_drone_gibs, which can be set to 0 to disable some graphics.
  • r_drawsprites and r_drawropes are no longer marked as cheats.
  • Added statistics support for the Football map.
  • Fixed exploits involving client commands (cl_campaignsas, cl_kickvote, etc.)
  • Fixed the warning message for an invalid unburrow idle activity.
  • Fixed a rare case where a marine dying would not automatically spectate the next marine.
  • Fixed the calculation of the fast hack time for 4-wire hacks.
  • Fixed scrolling the difficulty from Insane using keyboard or a controller going to Easy rather than Brutal.
  • Fixed not being able to draw on some parts of the map in the mission failed debriefing.
  • Improved physics calculations when a marine is stuck on a box or near a spawning alien.
  • Increased engine limit for pseudosounds, which are used for NPC AI.
  • Reduced the delay when starting a mission.
