I've been seeing teasers for this for some time now but they finally did an official release.
It's a fairly standard fps deathmatch game, but with all of the robot masters and their weapons from the Megaman series. Sure, there are better DM's out there... but how many of them have authentic NES graphics, music and sound?
You can grab it here (free!)...
(obviously Metalman is the best robot master... )
