Lowpoly Style Ultra Pack v1.21

Six packs in a single package! Asia, Desert, Woodlands ,Winter, Forest and Tropical Islands at an unbeatable price! Build your own environments with easy drag'n'drop: all assets come with a fitting collider and prefabs.
Or use the 6 vast, prebuilt demoscenes that are included (see the screenshots).

Performance: All 6 environments share 1 material and 1 texture, so you even can mix them and Unity can still batch the drawcalls together.
