This video should show you how to beat mission X-3 in Trauma Center without worrying as much about the Triti regenerating. Everything you need to know is detailed in the video.
Okay, 99.9% of the people that end up at this video are going to find this worthless, but I uploaded it to show a friend, and I didn't feel like making it private in case there were more people I wanted to show it to. So, don't give it a bad rating 'cause it seems like a pointless upload, please. XD And I know the model is crude. I threw it together in 1 night and it doesn't need to be pretty.
