Shipping a complete game without a day one patch is pretty passé, and true to that, the Evolve website describes how Turtle Rock will evolve the multiplayer shooter with its own day one patch. They say this will bring "big changes," which are all the result of the game's last beta test, describing balance tweaks, optimizations, bug fixes, new skins, and connectivity to the game's companion app. None of this seems dramatic enough to explain the size of the patch, which they say will be around three gigabytes, but maybe those skins are in 16K resolution or something. Thanks GameInformer.
