Biohazard Z War

Ammo's low, the horde's getting louder, and there's no pause button in Biohazard Z War — how many waves can you clear before they get in?

Biohazard Z War drops you into a grim little corner of a zombie apocalypse with one goal: stay alive. You move with WASD, aim with the mouse, and click to fire. Right-click zooms for a steadier shot, which I learned to rely on when a crowd starts shuffling in from all sides. The mouse wheel swaps between whatever guns you've scavenged, and hitting R when the slide locks back becomes muscle memory fast. There's no hand-holding here — just you, a handful of weapons, and the undead. What kept me coming back was the rhythm of it. Early waves are almost calm, letting you practice headshots and learn the map layout. Then the pressure climbs, and suddenly you're sprinting with Left Shift to grab a medkit while a brute smashes through the barricade behind you. The F key for pickups feels great when you snag a shotgun mid-fight, and G for grenades can clear a hallway in a pinch — but misjudge the arc and you'll just make the problem worse. It's not the prettiest zombie shooter out there, but it's snappy and satisfying. The ammo scarcity means you actually think about every pull of the trigger instead of spraying wildly. And that moment when you're down to your last magazine, back against a wall, and the round counter hits zero... yeah, that's when Biohazard Z War earns its name.

Aim for the head — one clean shot drops most standard infected faster than three to the body. Conserve rifle ammo in early waves; save it for runners and armored enemies that soak up pistol rounds. Use Left Shift to reposition, not just to run away. Kiting groups around obstacles buys reload time. Listen for audio cues before opening doors; a growl behind a barricade means a grenade might be worth it. Pick up health only when you really need it — medkits are scarce, and grabbing one at full HP wastes it. Swap weapons with the mouse wheel instead of reloading mid-fight; switching is often faster than waiting for the animation.
