It's very difficult to recommend Undetected, but only because I think its faults can scare off stealth fans. There's enough to enjoy about the game - the sound design and art are commendable given the size of the team. As an attempt to capture what makes MGS special, I think they succeeded.

However, the game comes with some jank, not bugs, that require you to understand how it expects you to play. This can be off-putting when you're expecting your reflexes from MGS to translate, and you have to meet the game on its terms to see what the devs have accomplished.

That may sound too negative. I do think it's worth a try, with interesting ideas that could be improved upon.
