Had that problem with Sasquatch for the longest time. He suffered a major injury during a mission and for some reason just would not get better despite having a doctor, medical tent, and plenty of meds. I had to reload a lot because he kept dying during sieges and my "Save everyone or you've failed" mindset wouldn't allow me to just move on. Explosives are handy for injured comrades and civilians. If they get swarmed, toss a pipe bomb and clean out any stragglers. Thank goodness for no friendly fire.
Ugh, friggin' Sasquatch. I have yet to figure out how the hell he expects me to kill a Juggernaut with blunt weapons, no guns or explosives. Damn thing just picks him up and rips him in half, completely shrugging off my character whacking it while it does so.
Anyhoop, started replaying Bioishock Infinite yesterday. 'Tis fun.
