The day has finally come for you to try out Mega Man Legends 3. Well the fan made 8-bit version of the game's cancelled Prototype, anyway. Get Me Off The Moon has released the concept demo, which includes a gauntlet stage requiring you to destroy 50 enemies as Barrett (the same showed off at Mega Rock Fan Festa).
It's important to note that the game requires your PC to be set to Japan regional mode to work, which you can do in your regional settings. You can also download a program from Microsoft which will let you run it without having to change your settings. Check the GMOTM post for more details on how to do this.
While I know some are tired of the 8-bit trend (I raise my own hand here too), Barrett's extended abilities give a nice twist to the classic formula, and I'm interested in seeing how they're put to use in other situations. It's definitely worth your time to try.
