For you Co-Optimers in the PAL region, this is an early Co-Op Release Alert, sort of - Operation Flashpoint: Red River will be available this Thursday, April 21st, as planned...for you. For us North Americans, the release date has been shot past May and impacted square on June 7th.
It's been a while since we've had any fresh coverage on Red River, so in case you've forgotten what it's all about, Codemasters has airdropped Co-Optimus a new co-op trailer. Trek on, Marine, and refresh your memory on the mission parameters.
