Yes, there's much more.

But it's hard to explain without spoiling things, as is typical for Kojima games. His games often feature unique and bold new gameplay, have a strong focus on character storytelling ( almost movie-like), all embedded in worlds that share many similarities with our own, but have bizarre twists to them.

In terms of gameplay, it has elements of survival, crafting, stealth, fighting/shooting, and navigation.

I consider Kojima games pieces of art. Not everyone will enjoy them, sure, but it's worth having at least attempted to interact with them, purely to experience their hard to forget uniqueness. Those that find the gameplay enjoyable often rank it as a game of the decade in terms of memorability.
