Easy, Medium and Hard difficulty, each with its own leaderboard. The other match options now sit in a “Custom rules” dropdown, and changing them makes the run unranked.
Medium and Hard:
You have less health, and upgrades take longer to earn (twice as long on Hard).
There’s no laser line to the crosshair.
Zombies spread out to surround you.
Armored elites with glowing purple eyes turn up.
Spitters aim where you’re heading.
The boss attacks more often.
Power-ups dropped by zombies:
Adrenaline: shoot about 40% faster for 15 s.
Speed Boots: run 30% faster for 15 s.
Armor Vest: has its own bar and cuts the damage you take until it wears out.
Max Health Up (rare): +10 max health for the rest of the match, up to +50.
Coin Pouch: +25 coins.
Team pickups that help everyone:
Double Points: score and coins count twice for 20 s.
Frost: every zombie moves at half speed for 8 s.
Shockwave (very rare): blasts away every regular zombie near you.
Coins: earned from kills and coin pouches. Half of what you earn is banked between matches, ready for map expansion and unlocks coming soon.
Skeletons (wave 6+): fast packs that fall apart and pull themselves back together unless you smash the bones or blow them up.
Mummies (wave 7+): wrap their bandages around you, slow you down, then drag you in. Shoot the cloth to break free.
A game over screen:
It shows the wave reached, team score, kills and revives.
Each survivor gets a row: score, coins, kills, best chain, revives, downs and upgrades.
The top scorer in co-op gets an MVP badge.
The host picks Play Again, Back to Lobby or Main Menu.
Lobby codes: every co-op lobby gets a 5-character code.
Invite Friends shows the code with a Copy button.
Friends type it on the Join screen.
Lobbies hosted by your Steam friends get a FRIEND tag and sit at the top of the list.
Spectate your teammates while you’re down. Click to switch between them.
When a teammate goes down, a “NAME is down!” alert pops up with an alarm. Skulls mark downed survivors on name tags, the team list and the edge-of-screen markers.
Twin Rockets and Triple Barrage upgrades: fire 2 or 3 rockets at once.
A bigger combined explosion when lots of things blow up together.
Blood spray and a soft hit sound when your shots land.
New boss sounds for the fireball and the charge, plus an “ABOMINATION DOWN” banner.
Players who join a match already going start with the team’s average upgrades, not just the pistol.
Press Enter to chat in co-op. It’s now on the controls card.
Zombies now claw their way up out of the ground near the walls, never right next to you.
Your weapons now fire over your own walls.
Fuel drums and mines can be placed about twice as far away.
A darker boss death: a dying roar, a ground-shaking collapse and a tolling bell.
New weapons wait in their slot instead of switching you to them.
A volley of rockets or a chain of drums now hurts a teammate like a single blast.
Arc Rifle toned down a little.
Team list health bars show how much max health your difficulty takes away.
Smaller, tidier menu and pause buttons.
Med kits glow green to match the minimap.
Difficulty descriptions spell out every change.
The boss’s floor smash had no sound you could hear.
Solo Medium and Hard started you at 100 health instead of 90 or 80.
A teammate’s name could show up misspelled.
The team list could overlap the wave number.
The med kit “+” on the minimap was off-centre.
The Steam friends list popup for invites, which could freeze the game. Use lobby codes instead.
Zombies no longer walk in through the gates.
The automatic restart after game over. The host chooses what happens next.
Coins can’t be spent yet.
If the host leaves, the lobby closes.
