Metal Slug 3 is headed to PC, according to a surprise addition to Steam. Konami popped a page up announcing a February launch, but hasn’t put a price or firm date on it yet. The 2000 SNK classic is already available on a number of older systems and modern digital portals. This version will have online co-op play, cloud saving, leaderboards and a stage select, and is being co-developed by DotEmu. No word yet on Linux and Mac availability.
