Duke Nukem: Critical Mass

Duke's arsenal includes pistols, pipe bombs, laser trip mines, Nordenfelt guns, a chain gun and various rocket launchers, but also his mighty foot to kick enemies.

The game sports a high level of interactivity.

Many objects in the environment can be broken or interacted with, such as pool tables, arcade machines, glass, light switches and security cameras.

The protagonist is also able to hand strippers dollars to have them remove their top.

The main character regularly delivers commentary on the events through one-liners.

There are twenty-eight levels, divided over three episodes, set in locations such as streets, a church, a space station, a Japanese villa, a football field and many modern environments.

Enemies mainly include aliens, mutated humans and members of the police force that have been turned into Pig Cops.

Next to weapons, Duke also has access to medikits, steroids to enhance his speed, night vision, protective boots, a hologram known as the "holoduke", and a jetpack to reach higher areas.

Most of the gameplay is action-oriented, but there is also an amount of puzzles needed to progress or access secret areas.

The game includes network play through the IPX protocol, for deathmatch and cooperative games.

While the port for the Sega Saturn features, among other things, a new secret level called Area 51, the Sony PlayStation version adds a whole new 7 level long episode called Plug 'N' Pray with new enemies and rearranged music.

Duke Nukem: Critical Mass for Nintendo DS is currently worth €51.06 loose, €27.95 complete in box, and €53.37 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Duke Nukem: Critical Mass has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Duke Nukem: Critical Mass, loose is €51.06 and CIB is €27.95 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Duke Nukem: Critical Mass is currently worth €51.06 loose, versus €80.45 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
