My favorite, CTF on Rubble. Type-7 is leaning against the wall in the structure above the center of the map. Just climb or way through there and look down in the corners as you go. Then stand on the 2nd level deck of your opponents base and shoot the booster to your far left. You can get a kill every 2 seconds, but the gun only holds 10 shots. When you are out, jump down and run over to the respawn point and refresh your ammo and go back to your balcony before respawning. WORST case they will respawn behind you and you have to aim through the window. Takes less than 10 mins to get your 50 kills this way.
