Did you know that when you ask AID about Tex the address he lives at is 813 Fourth St. When you ask AID about Sonny he also lives at 813 Fourth St. This is because Sonny just moved out. Remember how Sylvia said she found a scrap of paper on it with the address to Tex's Office. Carl didn't know Tex, but he did know Sonny, so Sonny used to live in Tex's apartment building.

    Take a look at the spray painting in Alcatraz, especially in Cell Block D. All those spray paintings that are names, are the name of people who helped make the game. For instance. In Cell Block D the most visible spray painting says "Cluff". This is the last name of one of the VR room designers.

    During the scene where Tex and Chelsee are looking for a parking spot, look on top of the Faberge billboard. It is kind of hard to make out but the red is actually the "Intel Inside" logo.

    The number 1024 appears at least 3 times in the game. You can find it on one of the keys Sylvia gets from the police, it is on one of Gideon's disks (the one you find in the hallway) and it is also on the laser torch you get at Alcatraz. The number 1024 (whether this be coincidence or not) is equal to a nice "round" binary number (the number system with only 1s and 0s): 1000000000. I have a feeling this number was used for that very reason (either that or because its a power of two, but the reason 1024 in binary is "round" is because 1024 is a power of two, but I won't get into that).
