PCG:Stealth Bastard is almost worth playing for its Metal Gear-baiting subtitle, ‘Tactical Espionage Arsehole’. Its mix of platforming and stealth, while both have been done better in more focused games, isn’t a bad reason either. It’s frustrating at times, but the kind where anything that looks impossible is usually a clue that you’ve not found the gimmick yet. A little more narrative wouldn’t have hurt, given the games in whose footsteps it treads. In the end though, you’ll be too busy dying to really care about the reason why.
