There are plenty of collectibles to find in Metal Gear Solid Rising: Revengeance. These collectibles can unlock new weapons or items, and they grant the player achievements and trophies. One particular collectible is known as ID Chips or Left Arms, and these collectibles must be severed off of various enemies in Blade Mode. There are 30 to find total, and getting all of them unlocks the 20 point achievement or bronze trophy A Big Fan of Lefties. You’ll also get the Infinite Wig A, Infinite Wig B, HF Machete, and Armor Breaker rewards. Need some help finding them all? Use our guide.

Tips

You will need to be in Blade Mode to slice off any limbs. The best way to get an arm off is to aim for the wrist area. Use a stealth kill for the best results, as this will make it easy to line yourself up. If you are in a group of enemies, take out the other guys first so you can focus on the Lefty. If you are having trouble cutting off the arm, you can always restart from your last checkpoint.
