Game Making Monster!

Massive Monster is an award-winning independent game development studio, creating games that are bursting with creativity, with a core focus on personality and play. We strive to squeeze every last juicy drop of fun and ingenuity out of every one of our monstrous creations.

Monster sightings have been recorded in our offices in Australia and the United Kingdom.

Cult of the Lamb casts players in the role of a possessed lamb saved from annihilation by an ominous stranger, and must repay their debt by building a loyal following in his name.
The Adventure Pals is an epic adventure platformer fueled by imagination, friendship, and the dark side of hot dogs. Your dad has been dadnapped and you, your pet rock, and giraffe must fight your way to save the world!
Never give up is a hardcore platformer determined to turn you into bloody chunks. Run, jump, and slide your way through ever-changing levels that get harder each time you succeed.
