The whole thing unfortunately, the game is mainly singleplayer but if I remember it needed to phone home before starting new missions on the campaign, so I couldn't actually play it once the servers died. This was a while ago so I could be misremembering but it was along those lines. Its a shame since it really was one of the best mobile games of that era, and came with a ton of content: 7+ campaign maps, each mission with an alternative "hero mode" which had completely different gameplay, Hell and Christmas themed modes, and tons of units, heroes, and spells to use. You'd only get to equip a few units and spells per mission, so trying out different combinations was important to clearing levels.
