In a strange world inhabitated by the weirdest creatures imaginable, peace could only last as long until somebody had the brilliant idea to create a crazed robot army. It's now up to the nerdy engineer Splee and her bulky pal Gløb to stop the invaders. In Splee & Gløb: Monster Defense, up to two players take control of the unlikely couple to fend off the invaders through clever tower-building and third-person combat in the most non-linear and asymmetric tower defense game you've ever seen.
The skilltree is the main target of your enemies and you have a good reason to defend it! The green gooey substance it produces is the lifeblood for all monsters you summon. And (surprisingly) the skilltree also allows you to upgrade and specialize your own skills or those of your fellow monsters.
