Nemesis 2 — About this game
Fly through side-scrolling enemy territory, collecting the red pickups that advance your power meter. Activate useful upgrades, from lasers to companion options, while keeping clear of walls and converging enemy waves. Bosses guard the end of stages. Some defeated bosses reveal a blue core: entering it opens an interior challenge with additional weapons to earn. Plan your equipment around the next passage and resist collecting so much speed that the craft becomes hard to steer.
