Great game. I liked every game Hideo did and I shouldn't have doubted this one. But I did, which however, caused me to pick it up for just 25 bucks 2 months after launch.
Its not for everyone, but it has all the Hideo Kojima traits. Enemies are weak to the MC's DNA. So yeah, pissing actually works. The traversal is the highlight for me. You'll struggle, and you'll get there. Then over time, by also raiding camps and looting minerals, the world gets infrastructure more and more you start it up. That struggle becomes an easy ride.
I liked it.
