Alphanauts are trying to survive an onslaught of strange black holes long enough to scan weird, dangerous rooms.

You control all of them - up to 26 characters! Simply press and hold a letter key to move the Alphanaut marked with that letter. You can control multiple little guys at once too!

The situation can go to hell pretty quickly - dying alphanauts form black holes too, and death will affect all the other characters on screen. Calling upon a dead character by mistake will cause painful memories to his grieving friends, plus his skeleton will rise from the darkness to attack his old teammates!

Survive as long as you can, as the black holes spread faster and more and more Alphanauts join the fray!

How to Play:

Letter keys (press and hold) - Control 1 or more characters
Arrow keys - Move selected character(s)
Enter - Start game
Esc - Quit to menu, Quit Game
