Once you've accepted the premise that the locals are strong enough to pierce metal with wood spears, it's an okay game. Definitely challenging. The tutorial is basically the toughest part. Once you can complete a mission with the worst gear possible, you can grind to your satisfaction to make the game much easier and pretty much WALK ON the rest of it lol !

If you like having to manage a ton and pull through a tough challenge, that game will do that.
