I have some Ideas for new weapons. For me they are more interesting than fixing lag. I believe that with different kind of weapons we can develop more strategies and have more fun.
1) Self Destruct Weapon
Once activated I have 10 seconds, a nice counter, and booom anything at a relatively range dies or get severely damaged... of course I will die too. The timer is good because then it's harder to do any attacking strategy. It should not be used as an attack weapon. Would be nice to see the counter on screen even by enemies, with a nice beep beep. Enemies should get some time to escape. If the damage is very high we should disable any key input, else we can warp to a enemy base just few seconds before blowing up.
2) Bouncer
Used like a RAM, but instead of hitting the opponent it just bounce him away a lot. In a team we can play socker with an enemy. Throwing into the sun or into a dangerous area. Or just away from us if we are in danger.
3) Wave
Anything at a short range get's damaged.
4) Bullet Bouncer
Any bullets/torpedos/mines/etc will bounce away from me. Good in a dangerous moment.
5) Bullet Inverter
Any bullets/torpedos/mines/etc will bounce away from me, in the opposite direction from where they where coming, but they will change 'owner' so hitting back the enemy.
6) Shadow Ship
If activated i have a shadow of myself flying around me at random. You must first guess which one is the real ship, in the meantime I hit you with the other one.
Maybe option to shoot shadow bullets too, same time I am doing.
7) Drop a Rock
The possiblity to drop a big rock in the space that doesnt move (or very slowly). I can bounce on the rock. And I can protect myself from bullets.

Wave weapon.
We have laser and bullets (torp, cannon, etc). But we don't have waves. A round line / arc going out from us. With a short angle. Like a wave.
This is for fun, graphical fun. Because basically the strategy is like with torpedoes and cannons.
9) Sabotage/Dropper
A kind of bullet that when hit will drop/sabotage one of your ship items. Maybe not always but at a 30% success rate. Dropping could be funny. But also a 1 minute sabotage is interesting. Because then I can attack you better.
10) Freezer
A bullet that when hit will stop keyboard input for 3 seconds.
11) Blind
A bullet that when hit will make your screen black for 3 seconds.
12) Whirl
A bullet that when hit will make you rotate on yourself like crazy for 3 seconds.
Such kind of weapons will make bigger ships more interesting because since they have more slots they can fit more than one.
just my 2 cents after two months playing
