Ideally, you have Mag weapons and predator armor by the time you're running into Mutons.
Holy shit, really? The first time I ran into Mutons, it was with a squad of 4, no upgraded armor or weapons. And I fought them a few more times before getting squad size/weapons. I'm just now researching new armor - as I'm taking on my first facility since the black site mission (which I did with a squad size of 5 and only an improved sword as a weapon upgrade).
Really glad I started on Veteran if that's the case.
I've only had one Chryssalid encounter so far.
It's where I earned the Now I am Become Death (kill 3 enemies in a single turn with a single soldier without explosives) achievement.
I earned that achievement on a technicality - I shot three Vipers with an acid grenade, and the next turn Acid Burn killed all of them. Technically wasn't explosives!
