Resistance Boosters are simply amazing against enemies using guns. What normally hits for ~32 health per hit now hits for 1; it's basically like having Immunity from the first Mass Effect. Combine with a Speed Booster (and maybe a Stamina Booster, too, depending on how strong your weapons are/how leveled up you are) and a healthy dose of maniacal laughter for best results.
Also, shoutout to MajorSlack for the shortcut during the escape sequence. Just make absolutely sure you take that little detour to the right after you climb up to the top so the checkpoint updates, otherwise you won't be able to leave at the end of the section.
