Primary fire:
The weapon will emit a concentrated beam of microwaves that will make your enemies brain boil until it explodes. The beam can also do damage to breakable props.

Secondary fire:
Shoots our a microwave grenade. The grenade can then later be activated remotely. Once the grenade is activated it will send out a burst of microwaves in a small radius. The microwave grenade is very effective at clearing rooms. You can not have more than one grenade out at the time. Launching a microwave grenade craves a lot of energy from the microwave rifle (500 energy units). If you can't launch a grenade it's probably because the rifle doesn't have enough energy or you already have one grenade out.

Reload:
The reload button will activate the microwave grenade. The microwave grenade will self destruct if you press reload again after the grenade is activated.
