Did Microsoft copy Descent 4 designs?

[Aggressor Prime]

I was just passing through some old Descent 4 stuff when I found some drawings of the Descent 4 jump jet suit that would have been used to jump jet from ship to ship. Then I began thinking of the new Mech Assault 2 from Microsoft. When I compared the 2 suits, they were quite similar. Take a look: Descent Suit 1 Mech Assault Suit 1 -You should notice the placement of rocket launchers on both. Descent Suit 2 Mech Assault Suit 2 -These are very nice. When looking at the Descent picture, pay close attention to the suit on the upper right hand corner. The 2 suits look identical. (Tubing and Claws) Also, remember that both games would have had / have jump jets on their suits. Also, it suprised me that Microsoft added a cloaking devise to this game. I bet they took this from the Descent series too. But that is less likely. The suits make me much more suspicious.
