Until now, the three released Fallout 3 expansions and the upcoming expansions have been Xbox 360 exclusives. Now, Bethesda has announced that all of these expansions will be multi-platform and coming to the PS3 as well.

Expansion Packs

1. Operation Anchorage
2. The Pitt
3. Broken Steel
4. Point Lookout
5. Mothership Zeta

These downloadable packs will start coming out in June. In October, a disc-based Fallout 3 GOTY edition ships with the game and all five expansions.

EDIT: These expansions were already available for PC. Thanks guys!
