Crypt Killer

To find them, you have to shoot your way through hordes of monsters.

The game has six stages which can be taken on in any order.

Each stage consists of four acts.

The levels range from dark forests to deep caves, ancient crypts and underwater labyrinths.

You move through the 3D levels on a predetermined path and shoot at skeletons, zombies, spiders, demons and other foul beasts.

Your standard weapon is a shotgun, but you can gain additional weapons like gatling guns and grenade throwers.

Some enemies throw projectiles like knives or bones at you, so be sure to aim at those as well.

If the screen becomes too crowded, clear it with a smartbomb.

At the end of some acts, you can choose from one of two paths through the next act, giving you different ways of completing a stage.

At the end of each stage, a boss enemy awaits.

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 Crypt Killer, loose is €33.00 and CIB is €83.45 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Crypt Killer is currently worth €33.00 loose, versus €26.73 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
