The RNG was strong with me today.
UFO defense mission, never had one before, its late game I have a team of pros.
I rush most of my team forwards and grapple my sniper to a vantage point. Trying to kill the beacon thing asap since it's an objective. My plan is to fire long range nades with my two grenadiers if I can do that. My sniper uses pistol overwatch, and my support dude has Ever Vigilent so he gets a free overwatch even though he dashed. Enemies run straight into my team, both overwatches hit the enemy Archon, take it down to half health. I lob a plasma nade to hit a couple of enemies.
My first reinforcement is my lightly wounded elite hacker. She successfully 35% hacks a sectopod to fight for us (unfortunately I already hit it with a plasma nade but it's still got most of its health and 2 armor).
The Psi trooper I brought with successfully 54% mind controls an Andro.
My sniper used serial to take 3x 95%+ shots, all of which get kills (thanks to the aforementioned grenade helping out by splash damaging a viper), then take a 60% Deadeye shot to OHK the Elite Shield-bearer. Then, since all 4 shots were kills, I got to reload my sniper rifle straight after all that too.
This is all second turn, have taken no hits yet because the enemies haven't fired. I'm almost scared to end my turn because this good luck is NOT going to last.
