Hold out. Find a way out.

Night Ops: Undead is a top-down co-op shooter for one to six players, set in the bunkers, trenches and steel corridors of a war the dead never left. Every round the horde comes harder and the map gives you a little more: a door to open, a gun on the wall, a perk, a trap, a crate that might hold something better. Board the windows, spend well, and keep the squad standing. Then find the way out.

The campaign

An unidentified signal has been detected inside a designated non-combatant zone. Your orders: find the source and destroy it.

Dark Operation was meant to be a simple night insertion. Then the helicopter went down short of the target. Get your bearings, get Command back on the radio, and complete the mission.

The zone is not empty. The local population is hostile, dead, and coming in waves, and every step toward the signal means digging in, arming up, and holding on. Reach the source, take it down, and get to the extraction point.

Can you and your squad get out before you're overrun?

How it plays

• Clear debris and open new rooms for weapons and space to move. Every opening gives you more ground to defend.

• Buy a Thompson or Trench Gun off the wall, or roll the Mystery Crate for a random weapon. The Beam Gun and Storm Coil are in the pool.

• Buy perks to take more hits or reload faster. Restore power to upgrade your weapons at the Punch Press, and put traps between your squad and the horde.

• Cover a teammate while they reload, revive them when they fall, and coordinate your spending to open the next door.

Game modes

• Campaign: Fight through the bunker, the convoy, and the radar compound, then make a run for extraction.

• Waves: Survive increasingly tough rounds with short breaks to reload and regroup. Hound rounds send fast-moving packs after your squad. Optional checkpoints give you another chance when a run falls apart.

• Overrun: No rounds and no breaks. Every kill brings more onto the map. Beat your kill record.

• Infection: One player starts infected. Bleed out and you join them. Hunt your former squadmates, or survive as the last human standing.

• DEAD PIXELS: Find hidden arcade cabinets and unlock retro versions of the maps with an old-school arcade look.

Six survival maps

A bunker, a trench network, a submerged U-boat, a flak tower, a mine, and a radar compound. Pick your ground in Waves, Overrun, or Infection.

The Armoury

Twenty guns, most of them from the war: the weapon manifest lists the M1911, Thompson, MP-40, PPSh, M1897 Trench Gun and two additional shotguns, Kar98k, M1 Garand, BAR, RPK, .50 Cal Machine Gun and a Panzerschreck. Buy guns off the wall for a known price, or take a chance on the Mystery Crate. Every roll costs points and is a gamble: a standard gun most of the time, or something rarer like the Beam Gun, Storm Coil, Scorcher or Reclaimer.

Every gun goes through the Punch Press three times. Each tier hits harder, holds more and reloads faster, and a few change form on the first press. Perks like Juggerbrew stack on top, and when a Lead Storm drops, the player gets thirty seconds of minigun action.
