UPDATE: We've been experimenting with a plugin called SuperNova (which you will be prompted to install upon attempting to load a game) and this has enabled some games to load, but the loading of progress is currently not available.

SAS Zombie Assault 4

New Event Mode! Virus Samples has been added to SAS 4. Kill zombies and collect the samples they leave behind, beat other players and win big rewards!

The year is 3104, and a virus outbreak on the trans-federation planet of Thera threatens the very fate of mankind. The only thing stopping this new and terrifying zombie horde from pushing mankind to the brink of existence is the highly skilled and highly weaponized special forces of the SAS. Choose from 3 unique character classes, and utilize the fully customizable skill tree combined with hundreds of weapons and armor pieces to build yourself the ultimate zombie killing hero. Play your way through 7 detailed and challenging levels in single player or 4 player multiplayer and save what's left of our ravaged civilization.
