Spin Tires had rather huge update recently, adding steam workshop support, new vehicles and features. Even tho steam workshop is not fully implanted, it's somewhat working and gives you a good idea of how it will work in future. Download + install mods straight from inside the game, no need to restart the game!
You can now choose which starting vehicles you want to have on any map.
I'm really excited about the steam workshop, it will be an epic feature once it's fully working, developers surely made a right choice by supporting steam workshop, they will get tons of supporters and game will stay alive for years!
Games die out because they get boring, but with steam workshop .. there will always be new and epic mods to test out .. and what better way to get them, than from steam workshop!! 1 click download + install .. epic, just epic.
Also they added a new vehicle selector menu.
I just hope mods will work online!!!
