On the battlefield of Counter-Strike 2 — Zombie Mode 1 / 2 / 3, Zombie Mode Z and Zombie Union War. Five classic modes, built on the SwiftlyS2 framework. The horde rises again; there is nowhere to run.
From the first night watch at ground zero to full-scale faction warfare — every horde you remember lives here.
The origin of every fear. A random host awakens at round start, and any human cut down by its claws joins the horde instantly. Limited ammo, no retreat — hold the last position, or become one of them.
The horde learned to evolve. Zombies mutate and level up through infection, gaining stronger bodies and abilities, while humans fight back with airdropped supplies and upgraded weapons. Tip the scales of evolution yourself.
When the survivors roar, heroes rise. In the endgame, a human may awaken as a hero unit wielding an exclusive artifact to turn the tide — answered by the horde’s surging rage. The final duel has no retreat.
Every round is a brand-new gene sequence. In-match leveling pairs with randomly awakened mutations — super jump, extreme speed, iron body… dozens of abilities combine freely to forge your own ultimate mutant.
No longer a game of cat and mouse. The human legion meets the horde head-on: capture strongholds, eliminate the enemy, and snowball your advantage. This is total war between two factions — pick your side.
