Just finished the hoth campaign and i must say us 2 rebels playing 2 figures and the empire all thought the last mission was impossible to win.

Has anyone ever won hoth as rebels ?

I don't think I've seen Hoth lost. The more open maps tend to favor the Rebels, snow troopers, wampas and the tank are pretty meh to begin with but Imperials also tend to get less threat given to them.

Rebs won the Hoth campaign that we played.

Had I not forgotten that Loku can fire through 3 snowtroopers with his valkaan, Imps would have won. Unfortunately, Sorin took one wrong move and was one-shotted losing the campaign for the Imperials

I won as the Imperial player in my campaign, mostly through Hired Gun spam, along with Find the Weak Point. Their team of heroes was also not the greatest, Verena, Gideon, Saska and Biv. Verena and Gideon had to pull most of the weight for the other 2, but at the end Verena got stuck having to solo against the tank. I think she got it down to like 2HP before my droids caught up to Biv hiding in the star destroyer and finished him off with a lucky ranged shot. It wasn't easy for me, had I held back even slightly I would have lost.

We won ours as Rebels (Fenn, MHD-19, Mak, Verena), but we felt strapped for cash and undergeared the whole time.
