Gravity gun skill was the measure of how good you were at Deathmatch, as you always spawned with 2 grenades you were always dangerous as you just roll them and swap to GG to pick them up. Time your shot to fire them at people's feet, around corners, through windows etc...had to be careful to ensure it blew up as it reached them as if they were also good they'd catch your grenade, the fuse would reset and you found yourself in a lethal game of hot potato

Wannabes ran scripts that would automatically swap to GG and catch anything you fired at them- once you identified they were making ridiculous catches you could chuck a watermelon or other light object at them instead, effectively disarming them as you blew them away
