Some Random Ideas
 

How about things like 'electro-coils' to buy, then plant which electifies the enemy if it comes within a set distance (It would have to be limitted to a certain amount of shocks).

Also a water map where you have to take the bases in the middle of the water. Water could be accessed with jet-ski thingies instead of the hoverbikes.

Enclosed are some illistrations of my ideas which describe these ideas in further detail.

Hmmm they could work similar to mines, may be longer distance, and they are not hurting but they disable your weapons (and jetpacks) for a few seconds ? We could also make electro-grenades


The bases are on little islands?

They are, only accessable but the jet-ski. Maybe have a few stationary Machine guns to man?

The vehicles must get some gun too then ?

If you like, maybe have it able for a second man to jump on the back and fire?

use those graphics for sure

I like the electro mines. EMP waves that disable electric items would be neat. Maybe it could stun the player for a second so it can be used for an ambush senario.
