This is the most stable version and there is no need to download any patches. However a # 'very strong pc' is require in order to run this version. If you know you don't have a beast pc then get the low res version. Low res is not that bad, but the low res full version require the v2 patch and this one not.
Fixing style that this version is old & outdated. Do not download this early version, as you will find no servers for it. Current version is Full Invasion 2 v0121 released December 25th, 2014. This is a multiplayer only modification.
