Run, gun, and get paid
Every kill earns money, because cash is the only driving force here. You sprint sideways through a former Soviet republic as a mercenary or marauder, trade shots with rifles and shotguns, toss stun and frag grenades, lay anti-personnel mines, and when ammo feels wasteful, settle it with a knife.
Skill matters more than gear: a good fighter can turn a round without firing a shot. It is blunt, quick, and a little scrappy, in pixel-art 2D with gore to match.
Tune your favourite rifle
The arsenal covers NATO and Warsaw Pact rifles, shotguns, pistols, sniper rifles, melee weapons, plus vests, helmets, and under-barrel grenade launchers. You pick the loadout, then improve stats with scopes, handles, barrels, receivers, mounts and bars.
Trophies can be collected and disassembled for new parts, which raises your Tech level. Win more, unlock more, and the best fighters climb toward the TOP 100 for a unique weapon set.
What else should you know?
Can you play it solo?
Yes. The tags list singleplayer alongside multiplayer and co-op, including local multiplayer, so you can shoot without rounding up a squad first.
How does progression work?
Kills earn money, trophies break down into parts, parts lift your Tech level and weapon stats, and strong results unlock more weapons over time.
Is there protection against better-equipped opponents?
That is the stated idea behind no pay-to-win: equipment helps, but a skilled fighter still has a chance, knives included.
What extra gear can you bring?
Bulletproof vests and helmets, stun and frag grenades, under-barrel grenade launchers, and anti-personnel mines, for surviving a bit longer.
