Artificial Extinction 2 asks a simple question. What if the machines you built to help you decided to end you. This 2026 tower defense RTS building shooter action game from 100Hr Games Inc puts you in charge of the last human bunker. You build your base, set up defensive lines, and then watch the AI horde approach. But you are not just a spectator. You can jump into a turret or pilot a mech to fight alongside your towers. The latest version of the game adds a survival mode where waves never end and you compete for the longest survival time.
