Fallout 3 features both new and old robots, including the handyman. It will also boast many new weapons, like the "Rock-It-Launcher," which is basically a toaster which can fire numerous items at your enemies. Fallout 3 also includes the ability to create your own items using a crafting system, as well as combine two weapons to make one stronger or more durable. Another cool new weapon is the "Lunch Box Explosive", which consists of a simple lunchbox from the pre-war days that is loaded up with explosives and can send your enemies soaring. Oh, and no, there are no drivable vehicles here — just explodable ones.​

...your father, one of the most important people in Vault 101...​

You have the option of triggering a detonator on the bomb and evaporating Megaton and the people living there, or reporting the shady guy to the sheriff and letting the law take care of the matter.​

As for the combat system, Fallout 3 will utilize the SPECIAL stat system employed by its predecessors: Strength, Perception, Endurance, Charisma, Intelligence, Agility, and Luck. You initially travel through the game in a real-time first-person mode, aiming your weapons like a first-person shooter and blasting away your opponents, but the cool thing about any title in the Fallout series is VATS (Vault-tec Assisted Targeting System). ... It is an innovative and exciting system to use in such a beautifully rendered 3D world.​

The demo showed off a few highly imaginative weapons, from the Suck-o-Tron, which lets you chuck useless items at enemies, to the Fatman personal miniature nuclear bomb catapult.​
