Laser snipers leave a trail of light, a rifle sniper gun would be interesting as it would be harder to determine the source. It would have to be high damage with a very slow rate of fire though if it was single shot.

I'm not sure if the game has the back end mechanic, but I would also say that it can't be used while moving, but you can get a gyro stablizer module that allows you to shoot while moving, but gives 1-3% boost to damage if you aren't.

I want burning plants with my flamethrower!

and hand grenades!

moar weaponzzz!!

lay mine fields around my plants i am growing

How about a close quarters voltage charge that stuns their mobility for 1 to 5 secs

Flame throwers should have ability to ignite plants. Burning plants will inflict AoE termal damage to those who's hiding there.

Also I like the idea of grenade launchers, nice medium range AoE weapon for missiles slot.

Stun guns.
Weapons that freeze the enemy.
Weapons that disables your system.
Magnetic gun that pulls the enemy closer to you or push the enemy away.
A system that can boost your speed for a few secs, used to ram other bots for dmg.
Electronic equipment that can make a mirror of your own bot.
Huge knife like weaponry, claws, hammers and spears to impale the enemy.
Acid spray

you should be able to target their wheels and tracks to stop them dead, then take over their bots!!!!

Once there bot is disabled and they try to leave the game they still lose the bot. or hit a button to blow it up, would be awesome to be able to capture bots

Your point on sniping is a good one, and that's why its good to talk about these things before they are implemented.

Sniping - Uses reversed Fall off; that is at optimum range you get max damage, but damage is reduced by the fall off value as target gets CLOSER.

Operationally - The Sniper fit has an optimal range which can be set while out of combat (a slider similar to the speed slider). Any hit within 0% (Modified by sniper skill up to 5%. .5% per level) off the selected range receives full damage (modified by armor etc). Any hit on either side of the selected range, and outside the sniper skill, is subject to fall off damage (modified by the fall off skill). Each sniper rifle has both a MIN and MAX range modified by falloff.

Tactically - Spotter gives distance to target, sniper sets rifle optimal range with slider. Target is locked and shot fired, if stationary and the rifle was dialed in, target takes max damage. Sniper is in combat and can not adjust slider. Target rushes in closer than optimal range, second shot hits but is subject to falloff. Target reaches MIN distance, sniper gets "Targe too close" error when trying to fire sniper gun.

Stragetically - with sniping ranges of 1500 meters or more, the sniper can be well out of range of the target but requires a target painter, just like artillary. For large scale engagements, the sniper is dependant on the spotter to anticipate target movements and relay expected distances, not actual. For solo play, sniping would happen at shorter ranges, 900m or so depending on target and installed detection modules. Sniper would have to continually move to maintain optimal distance, and be subject to moving penatly or have gyro stabilizer module.

Skills - Sniping is an advanced tactic that would require a well skill pilot. Target locking time would be a critical component, it should be as quick as possible since this warns the target they are about to get snipped, so sensor based skills for this as well as increasing your max locking distance; the gun gives a bonus but skills would be needed for mega-range shooting. Sniper weapon is a massive med weapon with high reactor, so typically only fitted on mech/hmech (also for increased sensors).

EDIT: So for a 1500 M shot and max sniper skill, target can be 1575 to 1425 and take full damage. So 5% maybe too low(.5% per) 10% for 1000M shots is 900-1100, a 200 M range, which sounds more appropriate.

artillery can me counter-sniping. if you see sniper is somewhere around, just supress his firepoint, devastate it with artillery cannons
