I've just played through rage, and while I am not crazy enough to go after some of the achievements, I was actually aiming for Three Birds, One Bomb Car and Hat Trick.
However, try as I might I couldn't set up a situation that would allow me to get one of these. Several factors contributed to my failure:
- It is very rare to encounter large groups of clustered enemies that don't try to immediately charge you (mutants) or go hide behind a wall (just about every other enemy).
- All enemies are clairvoyant, and know exactly what RC bomb cars and mind control bolts are, and so will try to shoot your RC cars/controlled suicide bombers.
- RC car bombs are amazingly annoying to drive, as they tend not to be able to go over most obstacles, even if they are incredibly low.
Any tips on how to set up a situation where these achievements can be acquired with relative ease would be appreciated.
