Shellshock

It has all sorts of locations including the main hangar, basketball court, simulation room, workshop area, briefing room and various lockers (used for loading and saving missions).

Before a mission, you can explore the headquarters and interact with each member of the team; you may learn something.

When you start a mission, the action is viewed from a first-person perspective.

It has you controlling the M-13 Predator, a highly sophisticated and upgradable tank.

The game is arcade-oriented and has much more in common with 'Quarantine' and 'Doom' than serious counterparts like 'M1 Tank Platoon'.

Your tank has unlimited bullets, can sustain heavy damage and can destroy enemies but also trees and buildings.

When a mission is successfully completed you earn cash which you can spend on repairing your tank and extra upgrades.

Shellshock for Sega Saturn is currently worth €28.27 loose, €15.44 complete in box, and €26.25 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Shellshock 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 Shellshock, loose is €28.27 and CIB is €15.44 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Shellshock is currently worth €28.27 loose, versus €23.99 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
