Fallout 3 - Preview @ Shacknews

Although labeled as E3 content, this Fallout 3 preview at Shacknews is based on the recent press junket at Bethsoft's Maryland offices according to the intro.  Anyway, here's a snip:

To really go to town with V.A.T.S., players will have access to a huge number of guns--some new, some old. By finding schematics and scavenging for parts, players can also create new weapons. The Rock-it launcher, for example, fires actual rocks or other bits of debris. Then, there is the Fat Man, a personal warhead launcher that actually creates a nuclear explosion just a matter of yards away. Taking a Vault-Tec lunchbox and filling it with bottle caps and explosives creates an improvised, but deadly, shrapnel bomb.
