OMD2 is a fantastic little indie arcade Ultima Underworld-lite Roguelite that comes abruptly to an end. No extra difficulty modes, no post-game content. Additionally, after you've played the game once, returning later doesn't prove particularly challenging at all after learning the nuances and bypassing the trial & error phase that any game presents. This mod is a simple yet transformative alteration of the game to keep it engaging for replays and well into the future. It will test both your knowledge of the game as well as your general action-RPG skill and decision-making. It's not all hard and scary though! Numerous perks, items & classes are improved for better balance and more interesting choices. Level design generation is more varied. A few bugs are fixed. Lastly, there is now post-game content in the form of unlockables for each class you beat the game with.
Numerous improved Perks for better balance. See the feature list.
