A name synonymous with PlayStation, WipEout is the rapid combat racer that defies gravity and defines generations. Known for its blistering speed, iconic music and pure multiplayer mayhem, WipEout has starred on every PlayStation format since 1995 - and is now set to rip through the air on PlayStation 4 and PlayStation 4 Pro.
Featuring all the content from WipEout HD, Fury and 2048, WipEout Omega Collection packs in 26 reversible circuits, 46 unique ships, a ton of game modes and some new and classic music tracks. It's time for WipEout veterans to come out of retirement and new pilots to make their debut.
