Ahaaa X-Com. Oh, for the olden days...
Anyway, Here's a few tips.
Heavy plasma wins. Get it.
Tech to laser rifles for a good alternative to HP Until you can get a steady income of ammo.
Get armor. Wub the armor. Give your best soldiers your best armor.
Don't bother with HWPs later on, They're useful at the start, and midpoint as scouts, but later on, your best soldiers are just as good, if not more. And as for scouting... that's what rookies are for, right? :whistle:
Pistols. Don't underestimate 'em. A heavy weapons soldier with no ammo is useless, But one with a good pistol on em can STILL kick some arse.
Go straight from the firestorm to avenger. Use
IT just as a tech link, It's useless, and can't even carry HWPs..
Even though I never finished it, I tried like hell and built a few tatics up.
