Wrath Of The Lamb
The bullet points on the Steam listing claim that Wrath adds 70% more content to the game. If that claim is true, a $3 expansion to a $5 game seems pretty reasonable. At first glace, the game doesn’t seem that different, unless you spawn in the cellar, the new alternate version of the basement. Each type of floor now has an alternate type that features a different type of monster focus, the basement focused on fly-type enemies and the cellar focuses on spider type. There is also a new final level that completing will unlock a new and truly final ending.
