Jurassic Park Part 2: The Chaos Continues/Track Down the Spy

This is a very straightforward mission with no surprises, but you must be very fast. The first time furrykef completed the mission (on easy difficulty), there was only one second on the clock! But if you keep moving, it probably won't come down to that.

Start out using the machine gun. When you come to the first ammo pack, switch to the shotgun before picking it up. You'll use it for the rest of the mission. There will be copious ammo along the way, so don't worry, even if you accidentally picked the first one up for the machine gun instead. (If you do, still switch to the shotgun afterward.)

Just move, move, move. If you get knocked down a couple of times or get hit by a couple of grenades, it's no big deal. Do watch where you're going, and especially watch out for flamethrowers, but they're not any more of a hazard than usual.

By the way, the mission description says you must capture the spy alive. Just to be clear, you won't have to worry about shooting him accidentally. Bullets go straight past him.
