Woops, I still need to add those to the game page!
Recommended Specs are:
Windows 7-10 (64 bit),
2.3 GHz (or faster) Quad-core CPU.
4GB (or more) of RAM.
DirectX 11 or DirectX 12 compatible graphics card, with at least 2gb of V-ram.
I ran it and it runs fairly good, a bit choppy during action moments, but I don't think it's the game causing that. For some reason, the look sensitivity was stuck at 0.5, so it was difficult to move around. I did get through about 3-4 levels despite that. Couldn't find any bugs besides clipping and objects/SWAT guys stuck in floors or walls.
I do like the Half-Life inspired mechanics too, especially the gravity gun hand thing going on and the health stations. Pretty cool game overall!
