Series 1000 shelter

The Series 1000 shelter was a type of a nuclear fallout bunker designed by the Vault-Tec Corporation.

Background
It was a one level, extensive subterranean installation, of which the exact purpose is unknown. Its blueprint is used as the town map for Vault 15 in Fallout 2. The Series 1000 shelter appears to be a basic shelter that can be set up at very low cost, providing far poorer protection than a Vault.

Appearances
The blueprints for the Series 1000 shelter only appear in Fallout 2 and is mentioned in Fallout 2d20.
