Expertise:  Im know nearly anything about the Tom Clancy game splinter cell. including Essentials on PSP. I can also help a little with Chaos Theory on Nintendo DS. If you have a question to do with any download levels for the first splinter cell please quote the whole name of the download as different sources have different names I will need to make sure i'm thinking of the same level. I'm sorry to say that for the time I can't answer questions about the new Splinter Cell game until I have played it myself although I do know what the game is about so I can answer that.

Experience in the area
I have been playing the splinter cell games since they came out and completed them all on multiple consoles. I have competed in many competitions and tournments, many i have been 1st or 2nd.

Education/Credentials
I only know from experiance
