New maps, even if they are just cut from the current maps
New new maps: Cave map, volcano map, super mountainous map, map that has a day/night cycle, map that takes place inside a storm, hurricane map
New environmental hazards (to go with the new maps):
Heat/fire hazard (sets fires on ship+direct fire damage)
Electric hazard (disables components temporarily, prevents them from being repaired)
Darkness (as in, need flares to see, not just to spot through clouds), Hurricane Winds (big damage to hull)
New ships: Ship with 2 front heavy guns, ship where the entire crew is meant to be shooting guns almost all the time (not like the Spire/Mobula where the pilot shooting is often optional), ship with an actual heavy weapon (I.e., the ship IS the gun)
New guns:
Heavy Gatling: Does the damage of 2 gatlings at greater range and accuracy, but with terrible screen shake. Has infinite ammo and instead operates on an overheat mechanic. Overheating doesn't immediately disable the gun, rather it does increasing self damage+fire stacks as long as the gun is used in overheat state.
Heavy Flamethrower: Like the flamethrower turret from Multiwinia. Uses overheat mechanic.
Burst fire assault rifle-type light gun: Piercing and shatter damage, with less piercing than the hades, 2 bursts to disable a light gun, 3 to disable an engine/medium weapon.
Actual flak gun, with airbursting rounds
New game modes: Throw in the standard ones from other competitive PvP games (e.g. VIP, juggernaut, bounty, FFA etc) plus some creative ones (still thinking about them)
Ironsights for all weapons so that proper no-hud can be achieved.
