While showing Kotaku a build of 2011's Bionic Commando Rearmed 2 last week, a Capcom spokesperson let me know that you don't need to jump in the new game. You can. The little hop makes it a little easier to get through Rearmed 2's tricky stages. You may play the game in "retro mode", however, which turns off the jumping.
You gain other abilities in the game, including optional passive attributes such as automatic health regeneration or an item-attracting tractor beam.
Jumping? You can skip it. This concept of adding a fundamental new move to a character who didn't have it for years - and then not making it essential - would seem odd, but only if this game wasn't coming from Capcom, a publisher that still can't gracefully address the conundrum of whether characters in Resident Evil should be able to run and shoot at the same time.
Movement changes are a confusing thing in the games of Capcom. So jump in the next Bionic Commando, or don't. Confused? At least Bionic Commando: Rearmed was a good game. Hopefully any confusion about this aspect of the sequel won't be a drawback.
Rearmed 2 is set for an early 2011 release as a downloadable game for PlayStation 3 and Xbox 360.
