Check out the old PlanetQuake page for 007 Q2 aka "Time Goes Backwards" mod for Quake 2 by IoN_PuLse - team leader, head coder, mapper, modeler, skinner, texturer, sound artist, etc.
It's 007 meets Quake 2! 007Q2 is the perfect mod to bone up on your skills at the weapons spies use. Weapons like the PP7, AK-47, and ZMG 9mm are what get the killing done, and a plethora of other guns and explosive toys to eliminate the threat were thrown in for good measure. Need to lay a trap for that enemy you just can't seem to kill? Try some proximity mines or maybe a remote controlled one, just to be extra sure. Gotta go somewhere high real quick? The handy dandy grappling hook will get you there on time!
