This fix maxes the FOV to 90, gives infinite ammo (it will regenerate ammo for every weapon every time you leave / enter a room or new area), and faster running and walking speeds.

Go to \steamapps\common\Lost in Vivo\LIV_Data\Managed (or the equivalent for your OS) and find the file called "Assembly-CSharp.dll". Rename or backup this file elsewhere.

Then download this file[disk.yandex.com]and put it into that folder, in place of the renamed (or backed up) assembly dll.

No other steps required.

If you don't trust random DLLs here[www.virustotal.com]is the virus total scan. Feel free to scan it yourself if you'd like.
