4. Three words: the gravity gun
The instructions are simple: point your gravity gun at any item not nailed to the floor, up to about the size of a car. Pull trigger. Watch it leap toward you and then hurl it elsewhere... and then smirk at the mayhem you’ve created. Now is your chance to chuck huge objects around the place to gloriously destructive effect; the gravity gun does as it says on the tin, and my goodness, it’s a fun toy.
