Shattered Pixel Dungeon is an open-source traditional roguelike dungeon crawler with randomized levels and enemies, and hundreds of items to collect and use. It’s based on the source code of Pixel Dungeon, by Watabou.

v2.4 features a new category of item: trinkets! They are more about tweaking gameplay variables than giving direct power or utility. There are also a bunch of smaller additions and tweaks, most notably to the Duelist and to Alchemy.
