"Oilrig" - On this level after you have finished of the men next to the helipad go into the lab and use the "Q-Remote" on the flashing green computer, now you can control ANY crane on the level. the first crane, outside the lab will drop a crate containing grenades, the second and third crane, accessible through a secret vent , this is at the second meeting with the boss guy, go left and use the laser on the vent, crawl through and open the big shutter door, then us the remote on the cranes and jump across the boxes untill you reach the land, then you can pick off the enemies more easily and avoid that sniper ! this also improves your points at the end of the level

"The Night of the Jackal" - when trying to reach the apartment use the Q-Claw to reach up onto the snipers balcony pick up his gun and this provies something to snipe men with and gives you a bonus points at the end of the level.
