Side-by-side comparison of features, pricing, ratings, and alternatives.
In 2012 a team of U.S. scientists brings back a mysterious metallic sphere from Mars, only to unleash a portal to an alien world in the secret underground facility known as Corridor 7. As a Special Forces agent you must battle through overrun hallways, eliminate the alien hordes, and stop the invasion before humanity is doomed. The game blends classic first‑person shooter action with a tense sci‑fi narrative, offering both single‑player and multiplayer modes on PC and Mac. With retro graphics, varied weapons, and a maze‑like base to explore, Corridor 7 delivers a nostalgic yet intense alien‑fighting experience.
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.
