How about laser cannon that fires a laser beam that comes in thee colors Blue, red, and green. Blue is cold, Red is hot, Green is basic energy damage like twins but as a constant beam that recharges like flame thower. 40 damage per second Glue gun fires Glue that make an enemy tank unable to move turrent and or tracks. It aslo has a corrosive that slowly does damage to an enemy tank over time. Thor: A lightning cannon that shoots out yellow electricity at an enemy tank. 100 damage per 3 seconds. Microwave cannon: This energy beam does damage to an enemy similar to a freeze ray but instead of cooling it can disrupt firing of a tanks turrent. About 10 damage per shot every second. Emp: This guns does little damage but will immobalize an enemy tank to where team mates can take it our with ease. But the effect last one minite. Nuke: ever set off a fire cracker well an atomic bomb will kill most every thing on the map. May be better suited as a power up. Toxic waste gun: By fireing out a sludge of toxic goo it stays on the ground for five minutes to ten depending on thickness. It will do damage to tanks that go through it in the amount of 10 damage per second. Seeker rockets: Smart rockets that seek out enemy targes from long range and explode near target doing wide area damage in the amount of 40 for indirect to 200 for a direct hit. Drone launcher: This is not a gun but fires out mini spider bots that seek out to tear apart an enemy tank. Each bot does 70 damage per second fires four drones at a time but refies every 20 seconds. Drons are small but can be easily destroyed as they only have 20 armor. Nuclear Reactor: A tank that uses radation from a reactor to make a 360 arc of radation that does 50 damage per second. Range is only 10. Anti tank Gun: Fires a laser guided missile that does 400 damage range 200. PSG5000: Plasma cannon that does 1000 damage over a range of 30 refires every 8 seconds.

What if you could buy internal parts for tanks. Computers increase acuracy and you can upgrade the computer and it inceases fire rate. Auto loader increases cannon refire rate. Capacitors upgrade energy weapon fire rate or fire power. And generators increases tank power. Forexample 6 cylinder diesel, adds 1000 to a tanks power. An 8 cylinder adds 1500 power. Turbine adds 2000 power. These can be transferded or chanded on your tank. Also fuel cells 3000 power to tank. 4000 from thorium flouride reactor. 5000 power from fusion reactor. Also when your tank gets damage or blows up if thorium salt reactor is pierced you leak radioactive salt that does radation damage to tank and enemy tanks. Actinide cannon is a nuclear waste at enemys does 1 damage but persist over a minute doing 1 damage per second. Laser beam does 100 damage but based on capacitor power. Note that more power means faster recharge for energy weapons. As for tanks maybe add wheel tracks, Half track and maybe hover. I think it may be a good idea to add rockets, Or just have a tank that shoots out a acid clould or spray. I think it may be neat to add different tansmissions to tanks to upgrade the speed. You have gear box, hydraulic transmission, and have a ferro fluid transmission. Then have a magnetic transmission, frictionless transmission, and finaly Super conducting motor transmission. Maybe double turrents where a smoky would be double. But only can be equiped on wide body tanks. Or have super heavy tank bodies that are Gargantuan, and Beheamoth that would be wider than Viking or Mamoth tank bodies. I think there should be a diamond power up where boxes have diamonds early in the game to encurage upgrading of tanks.
