My suggestions:
- The Laser Sniper should have a very long reload time, and should leave a colored streak after being fired, so that you can trace the original firing location.
- Each Laser Shotgun particles should do mild damage, but enough to make it formidable in close quarters.
- The Laser Pistol shouldn't have a scope, it just looks handicapped, it should do slightly more damage than a normal Pistol, and if you're up to it, you should do an edit of the Dual Guns addon and make Dual Laser Pistols.
- The Laser Auto-Rifle should be a good bit weaker than the sniper rifle, but much stronger than the pistol.
- The Laser Pusher should be an Anti-Tank type weapon, that does lots of damage to vehicles, but infantry damage is just a bit more than a few pistol rounds.
- The Laser Cannon (CANNON!) should be an Anti-Brick weapon, that has a large blast radius, but does medium damage to vehicles, and mild damage to infantry. It shouldn't do mountains of damage, but enough to seriously bust open the front of a building, and maybe take out some players inside.
BTW: If there is recoil, make sure that the weapon isn't fired while the gun is pointed in the air, if you've seen VH's M4A1, you'll know what I mean.
