Astro Buddies

Build a squad of cheerful aliens and defend five lanes against comets, crystals and meteors. Your defenders shoot automatically, while you decide who to recruit, where to place them and when to merge.

Combine two matching defenders into a stronger one and develop your squad up to rank eight. Each wave brings a tougher challenge, and every enemy that breaks through costs a life.

Spend earned coins on permanent upgrades to damage, income and health. Your upgrades and best wave carry over between runs. Find your formation and see how long you can survive!
