I hope you're enjoying xcom as much as I am. I see people playing on youtube and thought some of you will appreciate insight in true military style tactical advice that may help you. If you have more ideas I would love to hear them aswell.
#1 make 2 teams one is going to be a flanking team and the other the base of fire. What is the base of fire? Guys like the heavy or suport that can use suppressive fire
#2 in true military fashion why do we use suppressive fire? to keep our enemy from moving. We do this so that our second team can flank them from the left or right taking their cover away.
#3 clearing the room with grenade. You dont want to send in a point man in there to get shot? Why no send in our rockets or grenade in there to recon for us...who knows you might get some of them then clear the room. work each room as a team
#4 why not bring your grenade? the enemy has high HP and is in good cover toss a grenade destroy his cover then shoot his alien butt you'll have a better shot
#5 for each team always have a back up watching your ass USE OVER WATCH
#6 RECON go find where they are come back regroup then assalult your objective
#7 Play it like your there HOPE is not a course of action plan plan plan gather intel come up with a assault plan then execute guarantee you'll bring your boys and girls fighting for earth home safe to their families right?
