No, its becomes frustrating if (1) You dont use the right weapons (2) Don't comminicate to coordinate supers & grenades (3) Don't have a minimal understanding of the strike & the mods (so) you know in which bunkers bosses are & know they have to go down asap >> no standing in the back with a pulse. You should have no problem making it within the time without even to much rushing. - AR/SR - 3 Uriels (Arc - for those pesky harpies) - Rocket launchers.
