The Ultima Underworld games are some truly classic RPG dungeon crawler. And while series like Legend Of Grimrock have aimed to modernize that style, we are long overdue for a true follow-up.
Ascendant has been in development for quite some time, and frequently feels like it's dead. But thankfully a new developer update just arrived earlier this month.
The draw to this particular underground crawler above any other is in its focus on "unexpected customization". The game is designed around the player discovering many different ways to tackle any problem, even using methods the developer doesn't intend.
