One more taken for a ride (lalalala-lalalala)
Consider using the unconnected platforms for something else other than weapons, the Rocket Launcher is an important weapon in OA gameplay, so it should be easily accessible to everyone, bots included. Perhaps another powerup? The Quad is already overused, try something else, IDK, perhaps Haste or Regeneration?
The Shotgun should be near a spawnpoint, as it's a better weapon than the Machinegun. Since water is already an environmental feature (and should be classified under hazard as there is a risk of dying) what about placing something else here? The Lightning Gun, for example.
Finally, the lighting should be reworked. Try deleting all of the lights from your map and compile it only with the lighting emitted from the shaders and start working from there.
Thanks for these comments, sounds nice will use to change some based on your comments.
