- 5 Zombies & 4 Hell Soldiers spawn and will infinitely respawn when killed (4 Zombies & 3 Hell Soldiers for smaller maps).

--- The Stick Bombs mod has no change in mouse sensitivity, no FOV zoom, & its projectiles instantly explode on direct hits.
--- The Full Auto mod has reduced spread, increased range, no change in mouse sensitivity, & no FOV zoom.
- The Heavy Cannon base fire is hitscan.
--- The Precision Bolt mod FOV zoom is remove & it requires 10 bullets to fire (from 8). This was changed to balance out the increased maximum bullet count.
--- The Micro Missiles mod can fire 24 missiles before needing to reload, its projectile speed is 25% faster, & its projectiles instantly explode on direct hits.
- The Plasma Rifle base fire will increment in damage the longer it is fired. After 15 shots, the damage is increased by 1. After 30 shots, the damage is increased by 2. The Power Surge mastery damage will only increment by 1. This effect will reset after no longer firing the weapon.
--- The Microwave Beam (Lightning Beam) mod no longer reduces movement speed & it no longer locks onto a target. Instead, the weapon mod is a mid-range rapid-fire hitscan attack.
- The Rocket Launcher projectile speed is 33% faster.
--- The Lock on Burst (Charged Burst) mod projectile speed is 33% faster & it no longer locks onto a target. Instead, 3 rockets can be loaded and launched freely.

General Changes:
- Many of the Slayer's arsenal have received damage scaling that only affect an enemy Slayer.
- All Slayer are 15% larger & have a bright green render parameter attached to their render model.
- Audio & screen damage effects are applied to most secondary firing weapons to better communicate what kind of weapon hit the player.
- Playable demons instantly respawn. This was changed to prevent a bug where if a Spectator dies, a Slayer on the demon team would be unable to move for the respawn duration.
- Chainsaw kills will automatically give the player 30 health & ammo (instead of spawning loot drops). This was changed to prevent other players from stealing loot.
- Blood Punch kills will give the player 60 argent ammo (BFG/Unmaykr ammo).
- The Sentinel Hammer snares other players on impact but does not give ammo. Chainsaw or Glory Kill demons two times to recharge.
- Loot drops no longer seek to a nearby player. Instead, loot drops can be picked-up by moving near them. This was changed to mitigate loot stealing.
- All PVP loot drops last 3.5 seconds before despawning.
- The UI low health indicator occurs when the player reaches below 100 health. This was changed because players can die quickly in Slayer vs Slayer.
Classic Mode
- Hostile AI do not spawn. Instead health, armor, & ammo pickups will spawn throughout each map. Each pickup will respawn after 15 seconds (12 seconds for smaller maps). BFG ammo pickups will respawn after 60 seconds (50 seconds for smaller maps).
- Health pickups restore 25 health. Armor pickups restore 50 armor. Ammo pickups restore full ammo of their type.
- All Slayers have the Double Down, BFG-9000, & Unmaykr end-of-round upgrade unlocked from the start.
- Slayers do not have Blood Punch, Chainsaw, or Flame Belch. Melee deals 20 damage.
- Slayers start with 100% regular ammo & 0 BFG ammo.
Hunting Mode
- Players may teleport outside any campaign map (except The Dark Lord) & participate in a "hunting mode" where one player chases the other throughout parts of a campaign map. This is a sandbox mode where players may determine the rules/restrictions.
- Most entities are removed except portals, jump pads, & gorilla bars.
- Execute trigger hunt in the console to teleport outside of the arena.
- Execute trigger return to teleport back to the main Slayer vs Slayer arena.
- There are no resources in the hunting grounds; therefore, it is recommended for each player to execute the g_infiniteAmmo 1 command to disable ammo consumption. Execute g_infiniteAmmo 0 or restart DOOM Eternal to enable ammo consumption.
Client-Host Issues
- Clients may experience visual inconsistencies regarding AI and pickup spawn positions. This is due to positional "entity offsets" for network replicated entities, which only occurs to clients. The entities will appear roughly 5% closer to the world origin (x = 0, y = 0, z = 0). There is no known method to fix entity offsets.
- When a host Slayer is at max health or armor, and comes into pickup range of health or armor loot drops, clients may see the loot drop ribbons magnetize to the host Slayer. This is only a visual bug and does not impact gameplay.
- Sticky Bomb projectiles fired from a client Slayer will see the projectile pass through AI or players even though it explodes and deals damage. This is only a visual bug and does not impact gameplay.
- Heavy Cannon tracers fired from a client Slayer will deal slightly more damage against fodder than a host Slayer. There is no known method to fix this bug.
- The flame screen effect from the Meathook may not appear when a client locks onto another player.
- The host cannot see dynamic player outlines. Because of this, player outlines have been removed and replaced with a bright green render parameter.
- Clients cannot see some of the host's weapon projectiles, ribbons, or impact FX (they still function regardless). The following are not visible:
Sticky Bombs, Full Auto, Precision Bolt, Micro Missiles, Heat Blast, Lightning Beam, Lock-on Burst, Meathook Chain, Arbalest, Destroyer Blade, Mobile Turret, BFG Tendrils.
Other Issues
- If the player's FOV is above 120, chainsawing an enemy will sometimes reduce their FOV and prevent Precision Bolt zoom (the weapon still function none-the-less). Executing a Chainsaw or Glory Kill again may resolve this issue.
- When firing Charged Burst then immediately switching to a different weapon during the firing animation, 1 or 2 rockets will not fire. Wait for all 3 rockets to fire before switching weapons to mitigate this issue.
- A Slayer on the demon team will not show up in the podium intro and victory/lose screens.
- A Slayer on the demon team will not respawn when killed and the dead Slayer cannot spectate its living ally.
- Health gained by Chainsaw or Glory Kills may display +60 on the 1st-person HUD and look like it adds up to 35 health. Players will always gain 30 health and if they take damage or heal from a loot drop, their 1st-person HUD will correct itself. This is only a visual bug and does not impact gameplay.
- Blood Punch does not consume a charge or show a visual indicator when striking a Slayer. To compensate, Blood Punch deals low damage against a Slayer.
