Santa goes to hell

Every year just before Christmas, Santa and his elves march through the gates of hell to bring snowmen and cheer to the children of hell...

And every year the demons from the hell maintenance team are tasked by the devil, to beat back the horde of elves and deny respite for the sinners...

As a member of the hell maintenance team, it will be your duty to summon horrors of flesh and bone to defend the roads of the underworld.

This is a traditional tower defence game, with one unique twist. Instead of building different turrets, you will place upgrades/modules next to turrets to enhance them.
