The Binding of Isaac expansion released

There's surely no better place to spend your Memorial Day holiday than a dank basement, so slap down $3 for The Binding of Isaac's DLC expansion Wrath of the Lamb. Out today, it adds five new chapters along with new enemies, bosses, room types, items, and a new final (final) boss.

Wrath of the Lamb is sold through Steam for $2.99. Here's the official run-down on the the many, many shiny new things WotL adds:

• 100+ new items! (now over 235 items!)

• 5+ new chapters!

• 20+ new enemies!

• 25 new achievements!

• 15+ new bosses!

• 6+ new room types!

• 6+ new mysterious item drops (eternal hearts, playing cards, dimes and more!)

• 5+ new music tracks by Danny B

• A new item type, Trinkets

• A new challenge mode with 10 unique challenges that unlock more content

• A new unlockable character, Samson (The Beserker)

• A new final (final) chapter and boss with new endings

• Tons of new random happenings, curses, blessings, npcs, fortune tellers and more!

• Also more super secrets than you'd probably expect... good luck finding them all.

Which is certainly a respectable amount of content for three bucks.
