Fallout 3 — Broken Steel — an expansion for the first-person post-apocalyptic role-playing action game Fallout 3. You dealt a serious blow to the Enclave by launching the Purity project, but it still possesses immense power. The expansion begins immediately after the end of Fallout 3. You will work for the Brotherhood of Steel and must destroy the Enclave once and for all. You will be able to travel to new locations, experience new weapons, and encounter new monsters.
