I technically didn't pay anything for this game - I bought it as part of
Metal Gear Solid V: The Definitive Experience, which cost exactly the same as The Phantom Pain on its own. (For some reason.) If you really did get it for 40 dollars, well, I can only give my deepest condolences.
As a prelude, Ground Zeroes is pretty good. I had never played any previous Metal Gear Solid games, but from listening to the (surprisingly plentiful) cassette tapes while safely hidden inside a supplies room, I could get what 'the deal' was, to a certain degree. What really sells Ground Zeroes, however, is the atmosphere - the incessant rain, the cold military floodlights cutting through the night, the shadows layered upon shadows that feel like they could betray you at any moment. It's the kind of atmosphere stealth games were
made for, and the tension I felt crawling past silhouettes of guards and navigating across looming buildings was palpable, perhaps even more palpable than any tension the full game later presented.
Unfortunately, though, that's the thing: as a prelude to
The Phantom Pain, it's also a bit weird. The pitch black tone set by Ground Zeroes presents a benchmark that the later game never quite reaches - not that The Phantom Pain is
worse (quite the opposite), but it settles upon a considerably different mood; certainly a less asphyxiating one. Perhaps this can be explained by Ground Zeroes' much tighter focus on story, or The Phantom Pain's greater freedom of approach and potential for wacky hijinks - whichever may be the case, looking back I find it hard to connect both games to each other beyond the title and main character. Ground Zeroes finds itself in the odd position of being better as a standalone game than as a teaser for some other, rather different, game - while also being far too short to be taken as the former. As a two hour 'experience', though, it does almost everything right, and is a great appetizer for showcasing the smart and polished stealth gameplay you'll face in the main course.
still like a 6/10 in context tho
