Jurassic Park Part 2: The Chaos Continues/Weapons

Fight humans with lethal weapons, and dinosaurs with non-lethal weapons. If you kill a dinosaur, your dinosaur count, visible at the top of the screen, will decrease by 1. You will get "game over" if it falls below a certain level. (On "easy", that level is 35, and on "hard", it is 75.) The dinosaur count rises very slowly, but never exceeds 100. Killing raptors doesn't reduce your count, by the way, but it's usually easy enough to get rid of them with a couple of charged cattle prod shots anyway.

Lethal

 * Rifle: Unlimited ammo, but slow rate of fire.
 * Machine gun: Like the rifle, but with a much higher firing rate. You start with 200 ammo and get 100 more with an ammo pickup.
 * Shotgun: It fires three pellets which spread out. This is a slow weapon, because you cannot fire it again while your previous shot remains on the screen. (This means you can still fire it fairly rapidly from close range if your shots don't miss.) It's a very powerful weapon, especially if all three shells hit, and can kill the toughest raptors with about three hits. You start with 20, and get 20 more with an ammo pickup.

Non-lethal
Non-lethal weapons do not work on human enemies.
 * Cattle prod: Despite its name, it acts more like some kind of energy ball. It has infinite ammo. Hold to charge, and release to fire. Uncharged shots may still be effective against very weak enemies like pterodactyls and compies.
 * Tranquilizer machine gun: Same as the machine gun except it fires tranquilizer rounds.
 * Tranquilizer bazooka: Fires a potent projectile that explodes upon impact, causing splash damage. Comparable to the shotgun in terms of damage. Be careful, the splash damage from the tranquilizer bazooka will harm you if you're too close when it explodes. The shotgun is a better choice than the tranquilizer bazooka for taking out raptors in close quarters.
