CaptainToenail has recently released his latest version of the Heretic mod Quest for the Crystal Skulls. In this adventure, Corvus is confronted by a Heresiarch, a powerful minion of the Serpent Riders. This dark wizard has stolen three crystal skulls, using their power to open a portal to the underworld in the hopes of bringing about his master's return. Corvus must collect the remaining six crystal skulls in order to unlock the celestial path and confront the Heresiarch before it's too late. The mod is for GZDoom and features new monsters, a hub map system with 8 action-packed levels and a lot of new resources to discover.
