I've nearly finished the animations and AI for the next hostile alien life form Captain Moore will encounter. It's a pretty simple model (spherical), so the challenge lies in making it realistically roll around on the ground (hence the current name: Roller). Its behavior should lead to some interesting gameplay. When you (the player) get close to the creature, it sprouts small arms, which it uses to slap the ground and launch itself into the air at a random height in a random direction. It will repeatedly smack the ground and launch itself around until it finally strikes a ceiling surface. It then attaches to the ceiling and begins rhythmically launching balls of acid in a steady stream onto the ground below it.
If the player kills the creature before it sticks to the ceiling, it is harmless. But its acid is quite deadly and should be avoided at all costs.
