The second in the series (Hijack being the first), 'Escape' takes place in a supposed alien space station, which just happens to have a terran space vehicle parked out back.
A research facility has found an alien base on another planet. They aliens however fought back. They shot Duke out of they air in combat. Now he's really pissed off!
6 SP (1 secret) and 2 Dukematch levels. Features a new weapon (Assault Rifle replacing chaingun) and edited CON code to alter enemy strengths, ammo amount and weapon power. The levels end up leading you from an EDF facility to a secret installation and a prison until you reach a starport. From there you enter a spaceship where the showdown with an Overlord takes place. In the secret level, you travel to an arctic region via submarine.
8 new Caribbean levels (1 secret)! Powered by an awesome soundtrack contributing a lot to the "vacation feeling", you will pay a visit to lagoons, a Mayan temple, a fun park and many more places where shotguns are needed instead of sunglasses! Even features a mini hub to which you return to for about 50% of the episode.
4 maps which are more focused on design and combat. Like in its predecessor "Time", you still have certain things to do, but it's much less like a real mission.
3 objective-based levels (a fourth is unfinished and without any action). What makes "Time" special is its emphasis on objective-based missions. If you fail to complete an objective before finishing the level, you are sent back in time so you can try again. In general, it is more about evading traps and blowing things up than pure action
Contains 40 new levels, The 4 Lost Episodes of Duke Nukem, way back when he was still working for the CIA (see Duke Nukem I). Apparently, before the fight with Dr. Proton, he had fought off an alien invasion of Earth (though more in secrecy), the selfsame ones that tried again later during Duke Nukem 3D.
Duke has defeated the alien invasion force! What Duke doesn't know is that the force he defeated was the first wave and that the real armada is forming around the alien home world at this very moment! Providing 4 episodes with 24 levels, it is named by many as THE classic total conversion for Duke3D
