Hijacked is a horrible map with horrible spawns to start. You can spawn, walk 1/4th of the way across the map and get shot in the back from the enemy team spawning where you just spawned 40 seconds ago. Its a rusher's map. Try a danger close class with 2 bouncing bettys. when you spawn, toss both of them in high traffic areas in front of where you just spawned to where you know someone has to run that way to advance to the middle of the map. I've started doing that and getting 4-5 kills with it. It also gives me a good heads up when they start spawning behind me. Even if I don't get a kill I get tipped off when I'm notified that my equipment has been destroyed.
