HTO is a mini-mod which redesigns the trading system in Stalker as well as other gameplay elements related to looting and selling items. HTO 2.0 is an expansion expected to be released at a future date. If I abandon this mod I will not fail to let the community know first! So hang in there.
This is the Master Edition compatible with the Complete 2009 mod. I figured some people would want it. Also, in my other download file for the vanilla Master Edition, the readme says that it is compatible with complete, it is not, period. That's what this is for however, enjoy.
