I repaired the lift to the middle bridge, and now the ramp is almost aligned with the platform.

I tweaked more invisible barriers at red base in order tanks can't fire in the base too far in the distance, and changed the rock ramp to a metal ramp. in order to make tank driving smoother.

I will be scripting the big door on the far right of the map sooner than later.
please tell me if I should add weapons to this all vehicle based map.
