Super Fabricate

This perk grants you an infinite amount of frag grenades, smoke grenades and mines.
Strategies: 
Throw mines behind you as you walk. You never know when an unlucky survivr might accidentally step on it and go Boom! Just make sure to drop them randomly or you might just be leading your enemies to you.
Throw frags at hiding places (like bushes and tables) to flush out hiding survivrs. It is also a good way to take out your anger, because nothing beats throwing random frags all around the place.
When you enter the fray, start by lobbing some frags or smokes to confuse and weaken the enemy.
If you're surrounded by enemies, throw smokes all around you so it covers up a huge area, drop several frags, and leave at the last second. Leave too early and your enemies would chase you out; leave too late and you'll get blown up with them.
