Defcon 5 vs Marathon
Side-by-side comparison of features, pricing, ratings, and alternatives.
In Defcon 5 you navigate a maze‑like underground complex from a first‑person perspective, shuttling between manned turrets and the base’s interior. Your mission is to shoot down waves of enemy fighters, locate card keys, and manage the Virtual Operating System that runs the facility’s defenses. The game blends shooter action with strategic system management: repair damage, deploy robot sentries, and upgrade the OS to automate turret control. Ultimately you must secure clearance to self‑destruct the base, protect your escape shuttle, and survive the final escape.
Set in the distant future aboard the colony ship UESC Marathon, you play as a security officer tasked with protecting humanity’s first interstellar outpost. The game blends fast‑paced first‑person shooting with a deep narrative about alien invasion and survival in space. Originally released in 1994, Marathon pioneered network multiplayer and immersive storytelling, and it remains a beloved retro title available on modern Mac and iOS platforms.
