Melee weapon: FUCKING SWORD ARMS from Deus Ex:HR. Pretty much every day of my life I wish I had those, generally when dealing with stupid people. Bayonetta's hair is a close second.
Close Quarters/Crowd Suppression: UT04 Flak Cannon (FLAK MONKEY!)
Rifle: Overwatch Pulse Rifle (HL2)
Utility: Portal Gun (I was going to say the red gun from Antichamber but you can put portals underneath people's feet so that really swings it in the portal gun's favor.)
WMD: Katamari

3) Shrink gun from Duke Nukem 3d
4) The Nuke gun from Shadow Warrior...probably the most wtf overpowered BFG-style weapon ever and literally nukes most of the map (and you) if you aren't somewhere safe
