Three hard four my smooth brain.

The best tactical turn-based chess-like game in existence. Hard but fair, with perfect information about everything that's going to happen. No RNG involved, you only have yourself to blame. Can't stop till unlock all of the achievements.

This game's biggest failure is the mistake of putting players into unwinnable situations. It is one thing to lose based on skill, based on mistakes and based on ignorance. It is another to have the game decide 3 maps ago that your time is now and there isn't anything you can do about it. You don't have the kit, the squad, the moves, the damage, the health to overcome the map, and there just isn't anything you can do about it. It would be forgivable if it were more fun, similar to Darkest Dungeon, but the enjoyment of this game is strategizing, but you can't out strategize an unwinnable map - at that point, you are just wasting your player's time.
