Alien Swarm vs Shadowgrounds

Alien Swarm drops you and up to three friends into a hostile off‑world colony, forcing you to coordinate tactics and choose from four distinct marine classes. The free‑to‑play title blends intense shooter action with squad‑level strategy as you clear icy surfaces and lava‑filled mines of relentless alien threats. Beyond the core campaign, the game includes the full Source SDK code, offering developers access to a 3rd‑person camera, depth of field, dynamic shadows, and numerous gameplay enhancements for modding and custom content creation.

Shadowgrounds delivers fast‑paced, top‑down action set in a gritty sci‑fi universe, where players battle alien threats with a variety of upgradable weapons. The game features intense explosive combat, an innovative upgrade system, and a storyline that keeps you engaged from start to finish. The experience is enhanced by split‑keyboard or joystick co‑op, allowing two players to team up on a single computer, and it runs on Linux, PC, and Mac, offering broad accessibility for fans of shooter action.
