Gun Up

A zombie outbreak has overrun the city of New Horseon. With access to improvised and experimental weaponry, your only goal is simple: survive for as long as you can.

Core gameplay
Continuous enemy fight. Enemies spawn nonstop around you, with spawn speed increasing every wave. The old break-between-waves structure is gone.

XP and level-ups. Kills drop XP gems. When you level up the game pauses and you pick one of several upgrade cards: new weapons, perks, potions and more.

Card rerolls. You can reroll the offered cards (rerolls come from permanent upgrades).

Luck and Curse. Luck adds extra card choices and better drops. Curse makes enemies tougher but gives more XP, and it rises additionally on its own every 10 waves.

Two modes. Default (30 minutes) and Quick (10 minutes, same 30 waves).

Power-ups. Enemies can drop Max Ammo, Nuke, Magnet and Free XP pickups.

Regeneration. Health now regenerates after a few seconds without taking damage.

Player classes. SWAT, Thug, Worker and Teddy, each with its own health, energy and speed.

Sprint and energy. Running uses an energy bar.

Boss and escape
The Butcher. In the final minute everything else vanishes and the Butcher walks in. He has slams, leaps, bone volleys, ground-zone barrages and, later, a bullet ring. He gets faster and meaner in three phases.

Evacuation helicopter. If the timer runs out, a helicopter arrives and everyone has to get on it before the area is nuked. Killing the Butcher also wins the match.

Results screen. It shows time survived, wave reached, kills, damage, MVP and the coins you earned.

Weapons and arsenal
Many new guns. A large batch of weapons, melee weapons and utilities, all with new art.

Weapon fusion. Combine two weapons into one with a fusion screen that rolls the new stats. Certain pairs unlock special fusion weapons. Discovered recipes are tracked.

Auto-use systems. Pick passives that work on their own: automatic grenades, mines, shockwaves and a medic.

Utilities. Grenades, claymores, molotovs, monkey bomb, Infinibear, sentry turrets and stim shots.

Enemies
Bigger roster. Hasty, fat and tanky zombies, the Astro, Hound, Beastmaster, Shrouder, splitters, juggernauts, medics and more. Many have unique abilities.

Scaling. Enemy health and damage scale with Curse and with the number of players.

Meta Progression
Coins. You earn coins from damage dealt, with a bonus for killing the Butcher.

Permanent upgrades. Spend coins on base health, base energy, base speed, card rerolls, Luck and Curse.

Armory. Unlock additional weapons and utilities.

Achievements. Around 30 new achievements. Some unlock armory items.

Co-op and online
Co-op for up to 4. Downed players come back as ghosts and respawn next to a teammate after 60 seconds.

Smoother online play. Remote players and enemies now move smoothly even at low update rates.

Slow-connection friendly. The host sends each player only the enemies near them and lowers the update rate when there are too many.
