Scorcher takes out the muton with the rupture ability (she got it from the AWC) and the grenadier takes out an advent trooper with a lucky grenade from the evac point. Scorcher my bad ass combat specialist Lieutenant and a Squaddie grenadier start retreating towards the evac point. So I called in an evac near the sniper and have her retreat off the map. I figured all was lost as there was a big gap in my line where my 2 dead guys were and my sniper was exposed by themselves on the roof. I activated a pod that had a muton and 2 Advent troopers. I had lost 2 of 5 guys on my team (I'm 2 months in, predator armor but no magnetic weaponry built). Ignore everyone whining about the timers. Review summary: consult those strategy guides (there are plenty of spoiler free ones).
I had a fucking cool mission a few nights ago. Seriously, again, Im a noob to XCOM and to the genre and I found no issue with the timers, and all the mission types that are timed have them well-justified in my opinion. I had to do about a dozen runs that got abandoned 2 hours in before I got back in to my stride as I haven't played it since release :) I'm doing an iron man run at the moment on Commander (3rd difficulty, not sure of the name).
