New

- Guns are summoned, not carried. Press 1 or 2 to summon a gun and pay for it with your lifetime. It comes with spare mags, and there's no ammo to find. R reloads.
- Your own lifetime. Everyone has a 15:00 clock that drains faster on deeper floors. Enemies drop time pickups, and you can hold F to lend time to a squadmate.
- Hearts. Health is now red hearts plus blue armor hearts. Squadmates can't hurt each other.
- Throwing. Pick up bottles and bricks, or summon one on key 3, and throw them at enemies. You can throw your gun too, and a squadmate can catch it.
- Q skill. Choose the Totem (heals your squad) or the Barricade (blocks a gap) before the raid.
- E summons. Enemies drop charms. Take one, and E summons that enemy to fight for you.
- Extract keys. Every extract pad has a colour and needs a key of that colour. Keys drop on the floors below the surface. Hold F on a pad to open it for everyone.
- Bigger map. The surface is larger, every stair leads to its own cellar, the Sanctuary shows up in half the raids, and clearing the breach opens a second dive.
- Cars drive on new drifting physics. Space is the handbrake.
- Fog now hides players, enemies and loot, and your squad shares sight.

Removed

- Fists, ammo pickups, frames and timed exits.

Bug fixes

- Fixed errors and stutter in the fog after taking stairs or walking through a doorway.
- Gunshots no longer replay when a player walks into view.
- Kills now go to the player who actually made them.
- A loot pile can no longer be picked up twice.
- A dash no longer keeps going after you take stairs or walk through a doorway.
- Disconnecting now counts as dying, so it no longer keeps your loot safe.
