1. replace the terrible player models/weapons
2. add more reaslitic laser bolts and add decals.
3. improve the maps overall graphics.
4. change the death animations to be more realistic.
5. make vehicles better in terms of speed, handeling and modeling
6 increase the map headrooms and sizes.
7 make the gameplay more reaslitic by having better hit boxes ie why do you have to spray them like a water pistol just to kill someone. One feels exhausted after a game cus uve killed 10 enemies and shot your pistol/rilfe 500 times.
