I didn't think this game was very good. After exploring maybe about a quarter of the world I was already at the max level I could reach, had what I think was the best armor and weapons and had accidentally completed the main storyline which locks you out of playing anymore without a purchased upgrade.
So I went back to a previous save and tried to explore side missions but it just wasn't any fun when you're not getting points and when you found out something interesting there was no other characters to tell. It was hard to find enough characters with side missions and often those missions weren't important enough to be mapped so if you missed who you were suppose to talk to or where you were suppose to go there was no way to figure it out.
Example: A character said something like, "we aren't sure where the mutants are coming from and they seem to be looking for something in the city." Sound important right? Yeah. No mission. Found out how the mutants were made... no one to tell.
It's too bad because I started out liking it, but then it became pointless.
I have never been into shooter games until i tried fallout 3 game is neat its an rpg/fps and does a great job at both in my opinion I like how dark and gritty the game looks gameplay is legit has variety of enemies lots of free roaming only issue i had is no running other then that great game.
