[@Rithy] Yeah your character looks good to go with me. 

[@BurningCold] We know omni-tools can flash produce smart grenades and other projectiles but it would be very inefficient to try and use it as a substitute for a gun, since the tool would have to fabricate every round, fire it, and somehow balance the heating with a fire rate that would even approach useful. It is theoretically possible but it would be inefficient and impractical. 

[@Arcarius] You can drop a hint or two about his vendetta, and you can just put that he has demons hanging over him and he has unfinished business. You can save the biggest surprise for the game. 

[@PrivateVentures] Hmm I believe most of our reservations were addressed but I still saw a few references to nanites. I also think it should be further explained if he had biotics as a child and how he was able to train while he was bedridden. Other than that you look very well on track. Sam may have further words. 

[@The Spectre] Your sheet seems A-OK to me, just keep in mind that having strategic skill on paper won't automatically make him a good strategist. Sam might have more to say.
