Great Game.
It was a great game, and you are able to play effectively right from the start.
I liked the story, the art was good, the notes were funny, everything was great.
Although some things were odd, some weapons were clearly better than others, though you unlocked them earlier.
Best weapons: Uzi, Shotgun, Barrett (Pardon the spelling).
Were there any secrets? If so, I did not unlock any. I was gonna see if there was a secret if you beat the game with 100% health, but I was reloading my gun when a fat-fast person came out, I was able to shoot them once before they hit my gate, but they survived the barrett and hit me once.
It was a great game though, truly deserving of #1.
