I've had quite a bit of Berserker fun tonight. It's kind of like Ping Pong with a big red ball.
I also had another mission where I lured him in range of the squaddie with the Arc Thrower and managed to stun one.
I also changed by mind about CI. I decided to keep playing one of my original attempts without doing backups. I still hold the US, Europe and half of Asia (which means I lost the continent bonus). I've just hit September and my first Sectopod. Lost my Sniper to him and he was my 2nd Sniper after I lost my Major due to a stupid move triggering Heavy Floaters when I shouldn't have.
I have managed to get a Demon with Laser Cannons in each of the 3 remaining continents and have just got to the point where everyone has Plasma weapons and Titan armor. My sniper even has Archangel Armor with Advanced Flight researched and my only Colonel is an Assault that's just received an Alloy Cannon to play with.
So I'm not doing too badly, but I haven't assaulted the Alien Base yet. I'm trying to save that for when I NEED to in order to reduce panic.
I'm still a bit dubious about some of the "spawns" where aliens just appear out of thin air, sometimes in waves, but I guess it just adds to the challenge. I've had them appear right next to one of my soldiers though so not sure if that's a stupid game mechanic or a bug.
I'm still yet to try a SHIV but built an Alloy one and researched it up so might have to try and remember to take it on a mission at some stage.
