Here are two Crisis Suit conversions.
The first is my HQ that I made a couple years ago. I modifies the head, built a custom jet pack, gun, and blade. I plan to remake this variation with an attempt to add more detail.
The second one is regular battle suit with TL Burst Cannons. I really like how the jet pack turned out in this one. Not sure if the lower parts on the jet pack are additional thrusters, but I thought they looked cool when I put them on.
