I'm writing from Google, so there may be some glitches...
In general, the free version is terrible... I don't know what will be in the DLC, but after running around the empty map, I realized that it would be better if I didn't leave the base at all.
There's nothing to catch except the undead. I completed the Tutorial and... that's it! No saves, no interaction. From the fun, you put your slave in the choke and hit her on the spine until you conjure 100 hits. I thought it would be below the back, but when I saw the animation of hits on the back, I laughed out loud. No map, no transport, and yet there is a shooter here... in general, I don't know what the author of the game is trying to achieve, but there is simply nothing to do in his game. You just run around the map, shoot at dummies until your weapon goes haywire (yes, it does go haywire and stops shooting or reloading) and then you hit your slave on the back... that's the whole party. 3GB of pure graphics, which aren't even there, although there's no point in picking on them. It's not Skyrim or anything.
