After 27 hours, I have just beaten the main campaign, and I feel like I've barely scratched the surface of what one can do in this game. Stats like Chemistry, Hardware and Medicine could potentially be useful, but I wouldn't know, because I never levelled them. This game allows for a lot of specialisation, and there are many ways to alter the game's world and story through your actions. This game is pretty much the ultimate janky RPG, and I would thoroughly recommend it to anyone who loved the original Deus Ex, and is okay with the idea of not having straight-up stealth level design in a Deus Ex spiritual successor (it bugged me for a while, but Brigand manages to work well regardless).
