Bionic Commando Rearmed

This achievement requires that you block 100 enemy bullets with the Bionic Claw. This achievement will come after a short period of time while completing the game at higher difficulties but can be also be grabbed by crouching and spamming B with just about any enemy. I found that the easiest way to get this achievement on lower difficulties was to proceed to the end of Area 1 and fight the the D-1 Beetle Boss. This boss shoots a series of 3 Double Shot blasts (on Medium Difficulty) which are easily blocked by crouching on the upper platform and tapping the B button to deploy the Claw to block the bullets.
