If you haven't played Eurogamer's Bionic Commando Rearmed Challenge Room, then get right to it - and while you're at it you can also play through one designed by a Capcom fan.
As revealed on Capcom-Unity, Capcom follower Aaron Sedillo won the competition to design a Challenge Room. You can admire his sketch of the layout over there.
It looks painful - a difficult spike-sided descent and ascent sequence followed by steps, a back-and-forth swing sequence over a chasm and then a very delicate, lengthy drop ending in a right-angle swing through the end gate, which looks like it requires very precise timing.
To access the level, just enter the following cheats on the title screen:
Xbox 360 - Right, down, left, up, LB, RB, Y, Y, X, X, START.
PS3 - Right, down, left, up, L1, R1, triangle, triangle, square, square, START.
As we mentioned whe we talked about our own level, if you have a PC controller with the buttons set up the same way as the PS3/360 versions, you should be able to input the code the same way.
