He had great success with Call of Duty: Modern Warfare 2, winning the Gamestop 10k Tournament and placing T5 in the MLG Online National Championship.
Recently, NexXx has turned himself into a twitch superstar. With over 3.5 million views on twitch, he has certainly made a great Call of Duty impression in the twitch community.
NexXx plays mainly 1v1 and 2v2 gamebattles matches, while competing in professional tournaments when he can. The content you will find on his page is mainly great Search and Destroy tips for 1v1 play, amongst other things.
Feel free to follow him on twitch and twitter, but make sure to leave him some comments on the instructional videos he creates, and ask him questions. Enjoy!
