I bought I Am Alive for $19.99 I believe it was and thought it was pretty dope. Interesting and different. It's a Post-Apocalyptic game. Resources are limited so you have to spend a decent amount of time gathering any resources you can (bullets, food, etc). You also have to do a bit of planning when enemies approach as often times you'll have 1 bullet and that's it. You have to decide if you want to engage or just walk away (sometimes you have no choice).
There is also a lot of climbing buildings, but unlike other climbing games I am alive focuses heavily on your stamina. Your stamina drains pretty rapidly so if you run out, you'll drop to your death. You can use food/soda/etc. to give you more stamina or throughout the game you can find a few pins (can't recall the term right now) that you can hammer into the building and just rest hanging from it, which will allow you to regenerate stamina. So again, more planning when you climb. You have to make sure you take the fastest route or you'll end up wasting valuable resources or die.
The problem with this game was it was short as fuck, even for a $20 game. If it was longer, I'd give it a 4/5. Since it was so short, 2.5-3.0/5. I don't know if they are planning on releasing add on's or what, but it did have a cliff hanger ending so I suspect so.
For those considering buying the game - if you don't mind dropping $20 for a short game, buy it. If you value that $20 don't. I had fun playing it, just was very irritated it ended so quickly.
The whole game has a really dark feel to it. There is a massive amount of dust in the city
