Black Zero

A deadly agent called Black Zero has been sold on the black market. There is no cure. Fire is the only thing that kills it. Your squad is the only one trying to destroy it.
Black Zero is a top-down co-op shooter for 1–4 players. Play on the couch or online. You lead Wolf, a four-person special forces squad caught in a three-way war. A rebel army wants the agent released. A private military company wants it back so they can sell it. And the infected want nothing at all, except you.
Three enemies. One battlefield.
Rebels charge in and trade lives for ground. Mercenaries use cover, call out your position and flank you. The infected just keep coming. They will also fight each other, so read the battle and use the chaos.
Built for co-op
Play solo, with friends on one screen, or online. Enemy numbers scale with your squad size. Revive downed teammates, cover each other and push forward together. Playing alone? Bring AI squadmates you can order to hold, follow or take cover.
Four classes
Pick Assault, Gunner, Marksman or Medic. Each has its own weapons, stats and ability. Mix them however you like, even four of the same.
Game modes
Campaign: a story-driven mission campaign that gets darker the further in you go.
Horde: the infected come in waves, and every wave is bigger than the last. Choose how you play it:
Waves: hold out for 5, 10 or 20 waves.

Sabotage: plant C4 on four enemy targets, in any order. Every charge you plant brings the horde down on you, so defend it until it blows. Stall too long and the horde comes for you anyway. Destroy all four to win.

Team Deathmatch: squad vs squad, with bots filling any empty slots.
Earn and upgrade
Earn credits and XP in the campaign and spend them on gear between missions.
Four difficulty levels
From Recruit to Elite. Harder settings mean more enemies, smarter AI, stronger friendly fire and fewer helpful outlines.
