It's very difficult to recommend Undetected, but only because I think it's 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.

Portable Ops is an early mobile MGS only predated by Ghost Babel. Whereas the latter game was a continuation of the series' early MSX titles, Portable Ops aimed for something new yet familiar.

It didn't quite nail the goals it set out, but as I finished the game, I couldn't help realize how much ground work it laid out for Peace Walker and the eventual culmination of Big Boss' army in MGSV. A skeleton of what those games would become is here and it is rough, but the game is short enough to be inoffensive as another addition to the series.

The story manages to also play with some interesting ideals about a soldier's place in the world that give it that MGS flavor.

Overall, it's okay, but not awful.
