Antimatter Grenade
[/quote]

Antimatter weapons are OP and should be nerfed by reality. Antimatter-matter reactions produce more energy than nuclear fusion reactions such as in the friggin' Sun. A 1kg Antimatter grenade has a yield of 210 megatons. The largest nuclear bomb was the Tsar Bomba, and its yield was 50 megatons. An antimatter grenade shouldn't take out a 7 metre radius area, it should take out most everything within a thousand miles. And that's not to mention the ridiculous expense of actually producing and containing the antimatter in the first place.
