World War X

Merge your troops and command your armies. Crush real players in fast auto-battles.
World War X is a real-time PvP auto-battler that's easy to learn but hard to master — draft your deck, merge units to power them up, and outsmart live opponents in minutes-long matches.
⚔️ THREE FACTIONS, ONE WAR
Build armies from the Human military machine, the psionic Alien swarm, or the relentless Zombie horde. 25+ unique troops, each with its own role — from Marines and Siege Tanks to Zombie Behemoths and Alien Motherships.
🔀 MERGE TO DOMINATE
Combine matching troops mid-match to level them up and turn the tide. Unlock new units mid-match to counter your opponent. Every round you draft, merge, and reposition — smart play beats big spending.
