Kenshi is an open world, squad based sandbox RPG set in a brutal sword-punk wasteland. Gameplay is open-ended rather than a linear story, so you can play as a settler, a trader, a thief, a rebel, a warlord, an adventurer, a farmer, a slave... or just food for the cannibals.
But first things first, you need to survive. Train your men up from puny victims to master warriors, carry your wounded squad mates to safety and get them all home alive. You are not the chosen one, you’re not great and powerful, you don’t have more ‘hitpoints’ than everyone else and you are not special. Unless you work for it.
