Now with levels and their inside levels this would be awkward so it would be best to make the inside levels actually outside and have a roof over with the roof disappearing as you enter (like on sands of glory server)

With that said you can unleash total hell on the game!
Engineers can repair destroyed building and must do so to get inside them if destroyed. (due to rubble everywhere)
New weapon, Mini nuke! send it flying towards any base, however expensive. maybe 1000 or so? it causes a massivle crater effect. Grenades and rockets and such also do! Grab a tank and start plowing through those ice obstacles on iricia!
Imagine a new planet with a futuristic city? it fixes after every game but imagine climbing sky scrapers and building are collapsing around you. Your friend lands on helipad with his spaceship (2 seater) and saves your life? as you are flying do some air strikes and dogfighting. Maybe take out a few buildings on the way to expose camping snipers? the possibilities are endless.
That is how zone should be, absoloutely chaotic!

new vehicles for new planet levels. Spaceship fighters/bombers. Tanks. Ships (water) submarines (like ship but can go underwater and attack, weakness is bombers) Mini dropship!!!! (transport vessle capable of carrying 10 players! parachute out whenever you want or help gun the persuing ships with your guns. Or enjoy the show as the pilot drops bombs on the enemy bases below.
