Portalethium is a scifi based tower defense game made by the crew at CGCookie. Everything in the game was created with Blender and Unity. In a traditional tower defense sense, you buy turrets (weapons) that defense your towers (portals). You start the game off with a specific amount of credits to purchase the turrets and you must survive wave after wave of enemies both land based and air based.
