Skyraine is an action-packed missile defense game, developed by DHTstudios, designed for Windows platform. The game is set on an alien planet where players are stranded and have to defend themselves against waves of enemies. Players can use an ancient turret as their only defense against the invasion. The game progresses with the entry of new enemies, each with their own devastating weapons.

Players must collect supplies and power-ups to repair their base, between the waves of enemies. Skyraine offers different types of power-ups such as basic ammo, shotguns, discblades, vortexes, and zappy's, each with its own unique features. Players can also collect supplies like supply ships, ladders, girders, batteries, mines, autoguns, and zappy mines.

Skyraine offers local multiplayer options for up to three players to face increasingly challenging difficulties. The game's base is walled in between a shield generator, and players can expand the reach of their base above and below ground with the help of ladders and girders. Skyraine's enemies include bombers, spiders, suckerships, mech dogs, suicide ships, shield ships, transports, corrosive bugs, soldiers, and scorpions. Players must use their aim, precision, and strategy to conquer the final difficulty.
