Yaaaaaay for axes! Another question I forgot to ask. Are we limited to one mod per body location like in the games? Like you can have either Muscle Fiber Density OR Adaptive Bone Marrow in the leg area

No, you aren't limited to one per area like in the game and remember you CAN get creative with them if you'd like. The thing about how it's done in the game is an effort at balance. Lorewise, I'd argue that there was more than one, but in either case, the process is considerably better where our story picks up than it was when XCOM first started doing the gene mods.
