Space Guard: Alien Assault is a thrilling interstellar shooter defending space outposts from alien invasions. Move your spacecraft freely on screen and fire nonstop to destroy incoming alien swarms.
Defeated aliens drop shiny gems. Dodge enemy attacks while collecting gems to keep your health intact. Gems are vital currency for permanent combat upgrades.
Open the upgrade menu to raise weapon damage, fire speed and shield strength, plus unlock powerful special skills for tougher enemy waves.
When trapped by masses of foes or strong alien elites, grab floating power-ups on the field. Temporary buffs including shields, area blasts and speed boosts help you escape peril quickly.
Difficulty grows wave by wave, testing your reflexes and resource management. Stay nimble, upgrade rationally and activate buffs properly to guard your space base against alien attacks.
