Sector 781 is an arcade game with a pixel art design and catchy background music. This is a Metroidvania platform game, and combines elements of the classic games Metroid and Castlevania. Players must help an astronaut find the way through an alien space station full of robots, monsters, and traps. There are three realms to explore, and each realm consists of 25 screens. There’s a final boss lurking at the end of each realm. Players can activate checkpoints (the computer consoles) to save their progress, and gather up to 6 power-upgrades to strengthen their astronaut.
