ISC Avalanche is an independent game studio from Vienna. Our debut title, World Tree Defender - Seedlings of Yggdrasil, is a tower defense game that hands level design to the player: you shape every maze yourself from Tetromino pieces, then hold the line across three hostile biomes where weather is a mechanic, not a backdrop. At the centre stands the World Tree and the one thing you must keep alive. It is built to be played together. In co-op, two keepers defend a single tree and every placement becomes a conversation; versus modes, a loot system and a built-in map editor carry a run far beyond the first evening. Premium on PC (Steam), playable today, Early Access 2027.
