Play Air Fortress (Japan) Online

Air Fortress came out on the NES in 1987, developed by HAL Laboratory. It was one of those games that didn't get a lot of fanfare at the time, but it had a unique structure that set it apart from other space shooters and platformers on the system. You play as a pilot tasked with destroying a series of alien fortresses, and the game splits your time between two very different kinds of challenges.

You control a small ship, first flying through a side-scrolling shooter segment to reach a massive floating fortress. Once you dock, you leave your ship and continue on foot as a vulnerable astronaut. Inside, it becomes a methodical exploration game; you navigate room by room, avoid traps, collect energy orbs to power your limited shots, and hunt for the fortress core to destroy it. The tension comes from the self-destruct sequence you trigger, forcing you to retrace your steps and escape before the timer runs out. It feels like a careful, tense race against a clock you set yourself.
