Wait, what? Capcom made a Commando 3?

Capcom had an independent group design the new game, but otherwise... yeah. I think the demo isn't available yet. You buy the one download and then on a certain date--maybe now, since the game has been around for a week or so now--you will be able to (or can presently) download the beta thingy.

That's because you're too busy sneaking past peeing guards in little bathrooms!

Nonsense!

I was too busy fighting a masochistic ninja.
