Trams connect the maze-like living areas to a handful of manned turrets outside.

You must shuttle between shooting down waves of fighters in the turrets, and scouring the base levels for card keys during the down time.
A third consideration is the "Virtual Operating System" controlling all major base functions.
You use this interface to repair damage from attacks, monitor intruders, and place robot sentries to guard key passages.
As you find more access keys, you can increase the software's efficiency to the point that you can command turrets remotely, or set them to auto-attack with a high degree of success.
As defending the base becomes more automated and efficient, you have more time to search the levels for keys.
Your ultimate goal is to find the clearance to self-destruct the base, defend your escape shuttle, and get out alive.
About 3DO
The 3DO Interactive Multiplayer (1993/1994) was an ambitious, expensive CD-based console licensed to multiple manufacturers rather than built by a single company — a business model that ultimately contributed to its commercial failure. Low overall sales and a short commercial life mean 3DO games were produced in modest numbers, making complete copies a specialist retro collecting niche today.
Gamevaro tracks Defcon 5 for 3DO with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Defcon 5 to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This 3DO release dates back to 1995.

Rarity & condition
Only a handful of market sales have been tracked for Defcon 5, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common 3DO titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
