Persuadertron: This is the most important item of all. You use this to persuade common people, criminal, police, enemy syndicates, and scientists.
Pistol: This is the basic issue. Take advantage of the cheap price...FREE! Use this to save money.
Gauss Gun: A very powerful weapon. One shot costs 15000. When you shoot the Gauss gun it blows everything up in sight where the missle hits. EVERYTHING!
Shotgun: You get this developed at the start of the game. Shotguns are perfect when you need a little more firepower than the pistol. Beware of its shorter range.
Uzi: This should be the first weapon that comes out of research. The higher capacity and longer range than the pistol and shotgun makes it more tactical to use. Not very accurate.
Mini-gun: THIS IS ALL YOU WILL EVER NEED. The mini-gun is the weapon that will replace the pistol, uzi, and shotgun. Its extreme high rate of fire, ample ammo supply and very decent range makes it the weapon of choice. If you fire enough mini-gun rounds in a localized area, it will cause an explosion. Also good to destroy vehicles.
Laser: Expensive but effective. Basically vaporizes the target.
Flamer: Because of its extreme short range, the flamer is more fun than useful. Listen to them SCREAM!!!!
Long Range: This is the sniper's weapon. If the enemy has Long Ranges and you don't, you won't know what's hitting you. You can shoot off the screen with this one. Each shot isn't very powerful but LR's are cheap. Use the distance to keep yourself far away from the bad guys.
Scanner: Can't live without this one. This increases the area you can monitor on the map. Without it, you can't see squat on the map.
Medi-Kit: When your syndicates are about dead...Use the Medi-Kit to bring 'em back to life and another fighting chance. Option-click medi-kit heals all syndcates.
Time Bomb: Not extremely useful but very powerful. Drop these off when you want a "KA-BBOOOOOM!!!!" Command-click timebomb to drop the bomb.
Energy Shield: Makes you temporarily invincible to enemy fire. Use this as a getaway device.
