Slymoids

About

Slymoids is a 1984 action shooter for the TI-99 where you play a cowboy fending off alien invaders. The screen scrolls left and right as you move, revealing three distinct levels: a coastline, a cityscape, and a cavern with added hazards like dripping stalactites. You switch between aiming up to shoot airborne enemies and turning to face ground threats. Movement pauses shooting, so you must balance dodging and firing as waves of Slymoids approach from multiple angles. Starting at difficulty 1 through 4, you have three lives to clear each level before enemies overwhelm your position. The game stands out for its early scrolling mechanics and varied environments, which were uncommon for its system. The cavern level’s falling rocks add tension, while the three-location structure gives each playthrough a shifting challenge. Though short, it captures basic arcade shooter appeal with a retro twist. A niche pick for TI-99 enthusiasts, it holds a 3.2/5 average from retro gamers who appreciate its simplicity and steady difficulty curve.
