Zombie Infection publicity blurb

Zombie Infection is a community-created game mode added in Scream Fortress XV with the October 9, 2023 Patch. It features the RED team (also referred to as "Humans" or "Survivors") fighting to survive against the undead hordes of BLU team Zombies.

Introduction video

Gameplay

At the start of a round, all players begin on RED team and are given a small period of time to prepare their defenses. After this, a certain number of players based on the amount of players on RED team are randomly chosen to become infected. When a RED player dies, they are moved to the BLU team and play as a Zombie. BLU team wins if they manage to infect all Humans, while RED team wins if the remaining Humans hold out long enough without all being infected. Eight seconds are added to the timer for each RED player that is infected.

Humans

  • When there are 3 Humans left, all surviving Humans deal Mini-Crit damage.[1] When there is 1 Human left, the last surviving Human deals full Critical hits.[2]

Weapon modifications

Zombies

  • Zombies are mostly limited to only using melee attacks (doing 65 base damage), however, each Zombie class features a unique ability or passive.
  • Zombies cannot deal Critical hits, pick up Ammo or Health packs, and do not drop ammo on death (except for the Engineer if he has an unused EMP grenade).[4]
  • Zombies never take fall damage.[5]
  • All Zombies wear a Voodoo-Cursed Soul, have a green footstep Halloween Spell effect, and have a voice modifier applied that deepens their voice.
  • Zombies explode on death (dealing no damage) and drop a small health kit (Zombie Pyros drop a medium health kit instead).[6]

The number of starting Zombies is predefined for each team with less than 18 players. For teams with 18 or more players, it is calculated by rounding up the result of the number of RED players divided by 5.

Update history

October 9, 2023 Patch #1 (Scream Fortress 2023)
  • Added maps: Atoll, Devastation, Murky, Sanitarium, and Woods.

October 13, 2023 Patch

  • Updated zi_murky, zi_atoll, zi_devastation_final1, zi_woods[22], and zi_sanitarium
    • These changes are aimed to make playing as a Zombie more engaging, and to weaken the Human meta of bunkering without hurting their ability to roam and fight
      • Zombie Spy is now passively cloaked, only losing his cloak for 3 seconds when attacking or using his "Reveal" ability
        • This change will allow Zombie Spy to circumvent Sentry Guns that are watching large areas, and allow him to sneak into or around strongholds
      • Zombie Soldier's "Pounce" ability is now significantly higher, and has a 5 second cooldown (from 8)
        • These changes will bolster Zombie Soldier's role as a Recon pick and a roof buster, capable of launching through sentry fire
      • Zombie Sniper's "Spit" ability now damages buildables
      • Zombie Sniper now drops a puddle of spit on death
        • Both of these changes will make you feel like you're contributing more with your spit, and if that's not enough, you at least get to drop one on death to cause a small area of denial
      • Zombie Pyro no longer drops small health kits
      • Zombie Pyro's "Hellspawn" passive now releases a flaming explosion on death on top of the existing Gas Passer cloud
        • These changes should strengthen their afterburn capability, and make them a scarier threat if you let them too close
      • Zombie Heavy's "Tank" ability now adds the Battalion's Backup buff (immunity to Critical hits, 35% resistance to regular damage, and a 50% resistance to Sentry Gun damage)
      • Zombie Heavy deals 20% increased melee damage
        • Sentry and Crit resistance will bring Zombie Heavy's effective hp up much higher, buffing his role as a tank that you really oughta stay away from. His slower speed is unchanged, so you're still able to run. The changes will just make bunkering much more difficult with him around.
      • Zombie Engineer's EMP no longer rolls on shallow surfaces, and now does 110 damage instead of fractional damage
        • This change will turn EMP grenades into a much more immediate threat, instantly breaking mini Sentry Guns, crippling level 1 Sentry Guns, and wounding other buildings
      • Zombie Scout's "Speed Demon" passive now comes and additional 25% jump height boost
        • Zombie Scout already has a triple jump, but increasing jump height will make him even more of a pest buzzing around your head, and better at climbing onto roofs once a hold is destroyed
      • 1/5 of the server will be converted to zombies at the end of setup (from 1/6), and will also round up
        • It's become clear that there simply aren't enough zombies selected at the start of the round. Initial pushes should be easier to perform with a couple more units.
      • Sentry Guns deal 40% damage to zombies (from 60%)
        • Engineers are simply way too oppressive. The Dispenser is invaluable for the sake of ammo, and the sentry still has use as a knockback tool, but now should be significantly less frustrating to play against.
      • Demoman shield items no longer halve the damage taken by zombies
        • He was just too strong and incredibly unfun to duel. The extended reach of swords is already amazing against melee-only characters. His strong maneuverability is unchanged.

      • All Zombies except for Scout, heavy, and Spy, now have +25 HP (from +10)

Bugs

  • Afterburn caused by the Pyro Zombie's on-hit ignite does not trigger hitsounds.[23]
  • The game mode's HUD elements can sometimes fail to load, and a large black or white line appears diagonally across the screen instead.
  • The first person viewmodel arms can sometimes fail to load.
  • Sometimes, players may join the game as a spectator.
    • The Voodoo-Cursed Soul and green footstep Halloween Spell effect ends up wherever a spectator is currently looking, which by default is in the center of the map.
      • These effects may also merge with the player upon changing rounds, even as a Human form. This can also obstruct first person viewmodels if they are attached to the player. The Voodoo-Cursed Soul merged with a player does not match the class they are currently playing as, instead it is the Voodoo-Cursed Soul of the class they were in the previous round.
  • The Thriller taunt has a chance to replace the Zombie Heavy's High Noon kill taunt, when it does not normally replace kill taunts.
  • The Zombie Heavy swings slower than the other Zombies.

Unused content

  • Zombies under the effect of Jarate were originally meant to take Critical hits instead of Mini-Crits, as suggested by some commented out code.[24]
