bind "o" "say /"

1. Alien Expert
   • Description: Carries a Bio-Scanner that can scan nearby players and reveal their faction (Red: Traitor; Green: IAF).
     
   • Scanning has a cooldown.
     
   • For game balance, the first few scan targets are randomly choosen; only targets within a certain range can be scanned.
     
2. Biochemist
   • Description: Possesses two special biochemical agents.
     
   • Healing Vial: Grants hidden health to the target (except self), cures infections, and extinguishes fire.
     
   • Lethal Vial: Instantly kills any target (can select yourself as the target).
     
3. Colonel
   • Description: Acts as squad commander with extra hidden health. Hidden health is consumed right before your marine dies so that to save your marine, making you more durable.
     
4. Mechanic
   • Description: Owns a Mech that can reduce incoming damage when worn.
     
   • Limitation: Cannot wear it yourself; you can give it to a trusted teammate.
     
5. Sniper
   • Description: Excels at long-range precision shots. When killed, you detonate a final bullet that kills the killer, resulting in a mutual kill.
     
6. Explosive Expert
   • Description: Carries explosives; upon death, detonates your explosives, dealing area damage to nearby marines.
     
   • Note: Risks injuring teammates. Explosion damage falls off with distance; may not be lethal if far enough. Walls and obstacles greatly reduce damage.
     
7. Deserter
   • Description: In a near-death state, you flee the battlefield.
     
   • Gain 30 seconds of invulnerability (cannot attack or be attacked by other marines) to escape.
     
   • After invulnerability, your damage is greatly reduced for 90 seconds, then partially recovers but never returns to the original level.
     
   • Note: The HUD may show a player as "a Deserter in IAF Team", but they could be a Traitor (a Deserter abeted by Suborner). If used skillfully, a Deserter becomes a 30s human shield and a wild card on the battlefield.
     

1. Traitor Leader
   • Description: Similar to Colonel, with extra hidden health, making you more durable than a normal Traitor.
     
2. Suborner
   • Description: When Traitors are heavily outnumbered, you can convert one IAF member into a Traitor.
     
   • Note: Only possible if (Surviving IAF / Surviving Traitors) > 5/3 after the conversion.
     
3. Suicide Boomer
   • Description: Can initiate a suicide bomb attack; 5 seconds after activation, you detonate, causing area damage to nearby players.
     
   • Note: Risks injuring Traitors. Explosion damage falls off with distance; may not be lethal if far enough. Walls and obstacles greatly reduce damage.
     
4. Silencer
   • Description: Projects a unique bio-field that suppresses a target's active abilities, rendering them unusable.
     
5. Mimic
   • Description: Has a Quantum Holographic Cloak that causes the Alien Expert's scanner to identify you as an IAF member.
     

1. Starting Protection For a brief period after the game starts, all players are immune to damage from other players to allow developing strategies. The protection duration varies by map.
   
2. Grenades Grenade fuse times are lengthened to give players more reaction time, preventing instant massive kills and preserving the deduction core of the challenge.
   
3. Flashbangs The original flares have been replaced with flashbangs.[expand]
   • Detonate 2-4 seconds after being thrown.
     
   • Depending on face orientation, distance, and head obstruction, they cause varying durations and intensities of blindness.
     
   • While blinded, damage from sniper weapons drops to zero; other weapon damage is reduced accroding to the blindness intensity.
     
   [/expand]
   
4. Terrain-related Damage Reduces the dominance of high ground and long-distance sniping to avoid overpowered suppression.[expand]
   • When target's vertical height difference < 200 units and horizontal distance < 1200 units, normal damage applies.
     
   • When target's vertical height difference > 300 units or horizontal distance > 1600 units, no damage is dealt.
     
   • In all other cases, damage falls off gradually with increasing distance.
     
   [/expand]
   
5. Melee Knockdown Melee attacks have a chance to knockdown another marine.[expand]
   • Melee attacks have a chance to knock down the opponent, adding randomness and excitement to close-quarters combat.
     
   • Knockdown chance depends on the target's facing direction: lower from the front, higher from behind.
     
   • Wearing Power Fist significantly increases knockdown chance.
     
   [/expand]
   
6. Weapon Damage Balancing Using the 50CMG4-1 (.50 caliber heavy machine gun) as a baseline, other weapons' damages have been adjusted considering differences in range and bullet spread.
   
7. Parameter Randomization Certain parameters randomly change every 20s to increase overall unpredictability.
   

• IAF HAS42 Devastator: Pressing secondary fire now enters "lock mode", turning the marine into a stationary turret. This increases fire rate and bullet penetration. Pressing secondary fire again, rolling, using movement-causing offhand items (like the jump jets), switching weapons, melee attacking, or being damaged will deactivate "lock mode".
  
• IAF HAS42 Devastator: Slightly increased base damage so that both special weapons marines can kill drones on Brutal in one hit if all the pellets connect.
  
• IAF HAS42 Devastator: Reduced marine run speed penalty while deployed from 70% to 90%. For comparison, the autogun has an 80% penalty, and the minigun has a 95% penalty. Run speed penalty while shooting remains 30%.
  
• IAF Medical SMG: This gun is now more accurate while crouching.
  
• Made the EC-02 Stun Grenades (currently in development) available to all players for testing purposes.
  
• Fixed several types of non-Vindicator grenades showing the Vindicator grenade particle effect.
  

• Fixed several cases where Buzzers could get stuck inside the ground.
  
• Buzzers now activate based on proximity rather than when they can be seen by the camera.
  
• Increased Buzzer vision radius to 1024 units.
  
• Improved Buzzers' responsiveness to mapper commands like "Spread then hibernate" (they now move to a random nearby position before waiting for the player) and "Move to nearest marine" (Buzzers now periodically update the position they are trying to move to; before, far-away Buzzers could end up going to somewhere the marines left a while ago).
  
• Known issue: Buzzers with the "Move to ignoring marines" mapper command may continue to ignore marines after reaching their target.
  

• Jacob's Rest: Cargo Elevator: Fixed a supply box near the first door potentially causing marines to get stuck.
  
• Jacob's Rest: SynTek Residential: Removed an invisible wall near some biomass.
  
• Jacob's Rest: Sewer Junction B5: Fixed some alien spawn locations being embedded in concrete.
  
• Jacob's Rest: Sewer Junction B5: Fixed some buzzers spawning at the start of the mission rather than when they were intended to.
  
• Tilarus-5: Midnight Port Fixed a hole in a wall visible with rotated camera.
  
• Tears for Tarnor: (all missions): Fixed breakable boxes generating zero-charge combat flares.
  
• Lana's Escape: Lana's Maintenance: Fixed the "press top-right button" hint showing after the button had already been pressed.
  
• BioGen Corporation: Operation X5: Static sentry guns no longer deal friendly fire damage.
  
• IAF Marine Academy: Fixed skybox being too low in the lava arena. (This was causing problems with grenade launcher aiming.)
  
• Fixed alien and bot marine navigation issues across many missions.
  

• Added a "Thanks!" emote. (cl_emote 14) For now, the icon is only in English, but it will be translated later.
  
• Muting a player now also hides their minimap drawings.
  
• Fixed main menu performance issues caused by Workshop download state updating too often.
  

• asw_sniper_scope_radius is no longer cheat-protected. You can now make the Marksman Rifle scope hidden, or make it larger than your screen, if you so desire.
  
• rd_server_marine_backpacks is no longer cheat-protected. rd_client_marine_backpacks is now -1 by default (use server setting). rd_client_marine_backpacks 0 will now disable weapons-on-back even if the server requests them.
  
• asw_fix_cam is no longer cheat-protected. It can be used for freecam while spectating.
  
• Added rd_devastator_bullet_spread_duck convar (cheat-protected) for use by challenges.
  
• Added rd_botadd_sv console command for server operators.
  
• Added support for the AlterDeathMessage VScript hook function.
  
• Fixed memory leak in TraceLineTable VScript function.
  
• Added ForceSync() to VScript UI entities, which allows the client to discard its predicted state and go back to the last known server state even if the server has not sent an update yet. This is useful for client-side-only UI logic.
  
• Video files in addons can now also be webm files. Previously, they could only be bik files.
  

• [p]Added rd_lobby_query_servers convar (default 0 until the problem with the Steam API is fixed) to disable server list queries, which are currently not being properly filtered to just Alien Swarm: Reactive Drop servers by the Steamworks API.[/p]
  • [p]Note: This means that HoIAF servers are not labelled in-game currently. Progress is still tracked, and HoIAF servers can be found via the Steam Client "Game Servers" list or a website that has a server list, such as https://serverlist.reactivedrop.com/server-list, neither of which appear to be affected by the filtering issue.[/p]
• [p]Reduced the performance impact of the Steam Workshop download progress widget.[/p]
