Mega Man 10
is the successor to the largely popular Mega Man 9
, which was released in October of 2008. DLC soon came out for it, which included harder difficulties, the ability to play as Proto Man, and a new level that was endless. Mega Man 10
appears to be continuing this trend, with the game's endless mode being sold separately from the game, for the same price it was for the previous game: 240 MS.
On a positive note, the official website for Mega Man 10
states that Proto Man will be available from the start of the game, so at least we won't have to pay for that.
Regardless, Mega Man 10
will hit XBLA March 31st, and the Endless Mode DLC will hit some time after that. No word on whether or not the Endless Mode will have achievements or not, but if it follows in the path of Mega Man 9
, it will likely not.
