Got bored yesterday and decided to try to implement this new single-player game mode. Provided that there is one human player (and any number of AI players), Formless mode will make the human player play as Formless, and every time an AI bot dies it gets assigned a new random hero (no limitations, so any hero is fair game and heroes can show up multiple times). Every time the player dies, Formless loses all of his abilities after he revives.
Kind of a semi-dm type deal, except that Formless is a constant. With the cycling AI players, this should significantly increase the number of combos that one will experience in a single game.
Currently only in the incremental map, which I'll post later after some fine-tuning to prevent some leaks. If it's popular enough maybe I'll pop it in the release as well. =)
Was going to post it today but I found a pretty serious bug in the mode, it'll take a while to fix and I'm a bit busy today. Guess you'll all have to be patient. =P
