Crossfire

After the briefing you'll start out flying through a quick level in your helicopter, blasting everything in sight. You have bombs you can use, or a turbo boost that gives you temporary invincibility. Once you reach the end, you'll see a cinema of your chopper decending, and this is where the game gets interesting. You'll see a close up of your chopper at the bottom of the screen, and you get to fly over the enemy base basically killing everything that moves with impunity, you're invincible in the 10 or 15 seconds this part lasts.

Now you bust out on foot and run through the level like in Commando. The control scheme is pretty good, pressing back or back diagonally makes you shoot forward in the opposite direction, so you can walk backward and shoot everything ahead of you. You can shoot turrets that are up on ledges or walls. Calls in the chopper, your guy will dive onto the ground and you'll get the close up chopper view and be able to kill anything that moves for a few seconds.

At the end of each foot level there's a door you have to enter, inside is a super short level where you just need to find the hostage and kill a few enemies.

The coolest effects are how your guy actually gets bigger when he jumps, the up close view of the chopper, and the way the bullets ricochet with the Disrupt and Wave weapons, killing enemies with the flak. There's not really any flicker, and absolutely no slowdown even when there's about 15 little jets flying at you on the screen.
