Let's see, there were the Sectoids, the Reapers, and what other types of ailens?
I've got a few notes on this sort of campaign, all from the first game. Some lists that might be helpful:
XCOM craft - Skyranger (transport, no weapons), Interceptor (fighter, two weapons), Firestorm (advanced fighter, two weapons), Lightning (advanced transport, one weapon), Avenger (fighter/transport, 2 weapons)
First two are basic terran craft, other three use alien tech. Avenger is capable of interplanetary flight (it's the one you use to get to Mars).
XCOM craft weapons - Autocannon, Stingray missile, Avalanche missile, Laser Cannon, Plasma Beam, Fusion Launcher
First three are basic terran weapons, laser cannon is an advanced terran weapon, plasma beam and fusion launcher are alien tech.
XCOM basic infantry weapons - Pistol, Rifle, Heavy Cannon (ammo is armour piercing, high explosive, or incendiary), Auto-Cannon (ammo is armour piercing, high explosive, or incendiary), Rocket Launcher (ammo is small rocket, large rocket, or incendiary), Grenade, Smoke Grenade, Proximity Grenade, High Explosive
XCOM researched infantry weapons (terran) - Laser Pistol, Laser Rifle, Heavy Laser
XCOM researched infantry weapons (alien) - Plasma Pistol, Plasma Rifle, Heavy Plasma, Blaster Launcher, Small Launcher, Alien Grenade

Alien Species are:
Sectoids - the little gray guys
Floater - levitating aliens in robes
Snakeman - humanoid torso, snake "tail"
Muton - humanoid warrior race
Ethereals - robed psionics apparently behind the whole thing
Reaper - large furry bipedal creature
Cyberdisc - large floating disc with weaponry
Chrysalid - Ridley Scott-style alien that turns humans into zombies, which eventually become more Chrysalids
Sectopod - think this was kind of an armoured Reaper
Celatid - acid spitters
Silacoid - they get close and blow up
Hope that's useful!
