Recently made the mistake of trying a Stalker. I was getting used to the average of 3 deaths per mission, but then I hit the Defend TPN from Destroyer Horde mission. Wow, I never died, but it took me over an hour to complete. With running from one end of zone to other back and forth to try to heal and using the Blackwand veteran power over and over, I finally got it done.
There was a mention of a bag of grenades, but it doesn't give you a temp power.
My suggestion: auto-complete this mission if you have the option available.
