This mutator replaces all Flak Cannons with Sticky Cannons. The primary fire is the same as that of a flak cannon, only it fires a little faster. The secondary fire spits out pointy grenades that stick to players and walls/floors/ceilings etc.
The cannon itself requires quite a different strategy, because you can’t really run after your grenades. It is quite nice though, to stick a few of those pointy fellows into your opponent, and see them blown to pieces from several yards away :-) The grenades explode when damaged, so you can create a chain reaction by placing multiple grenades together ie. on a wall, and then shoot them with the rocket launcher.
