The True Abyss is a nice kind of "side quest" in the Secrets of Dyrt, and is available in both the original game as in this remake.

The True Abyss is not accessible from the normal game, but unlocks in the game's main menu when you solved a certain sidequest in the regular game (or in the New Game+). The True Abyss is an "endless" game. It just takes on for 100 randomly generated maps, in which you need to find the exit to the next map and to defeat the monsters on your way. If you play this subgame you'll have the entire group from the start, no scenario or storyline, just go on, as far as you wanna take it. When you reach level 100 you can just reset to floor 1, experience levels will reset, but learned abilities, and inventory will transfer, and experience will go faster. Just set your own goals in this place. You da boss now. Nothing special here, although some trophies can only be obtained here.

Once the True Abyss has been taken care of, my main concern will be to get the New Game+ in order. The New Game+ will just be the normal game with story line, although Eric and Seelah Gandra will have all their magic groups unlocked from the start (and ignore the impossibilities the scenario put into this), experience will go faster, and the game will contain a few extra side quests.

Once the True Abyss and the New Game+ have been completely worked out, the release of the first beta can draw closer. It will really depend on what I've left on my issue tracker then.

Oh you want one more screenshot... How about a screenshot of the code I wrote for the True Abyss?
