So far Halo: Reach is a janky, but still-enjoyable experience on PC. Right now Halo: Reach is far from the optimized experience that Industries promised. It's not a complete package and is missing many important features, like co-op campaign matchmaking, split-screen play, and basic progression schemes. But when it works, it transports you back to It's not a full total recall type of situation-you have to squint past a bunch of flaws-but it's good enough to keep you playing for hours and not realizing it. No campaign co-op matchmaking - The original Reach had every type of play covered, whether you wanted to play solo, with friends, or randoms. It had campaign matchmaking a first for the Halo series to let randoms team up and take on the campaign together.
