It would be great to be able to disable the weapon lasers with the left trigger.

It's very difficult to aim with the tank turrets; I don't know if it's intentional.

Adding weather effects like rain and fog to the maps would be fantastic.

A night map with night vision goggles and weapon lasers would be awesome!

The ability to pick up weapons from dead enemies would be great.

A Battlefield-style subway map would be epic!
