"
and a sawed off double barreled shotgun sidearm."
Ye for light body types who run real fast and wear baseball caps.
We could also have rocket launchers for heavies and a cloaking device for spie...ooops I mean operatives, and flame throwers for medium builds that also comes with a big red body suit and a gas mask.

Maybe new voice options like "Spy sappin ma sentry!"
Just messin with ya

I hope to see quite a few new weapons. I just hope that if this wish come true that they balance out with existing weapons and dont render them useless. Brink is a great game that has great potential if only for the reason that all weps get used. As soon as one becomes OP then everyone uses it and the game loses a helluva lot of flavour.
I would like Uzi's and Ingrams as light sidearms and maybe a HK MP5.
