The Half-Life series has the biggest and most loyal fan base ever formed for a game. Valve are aware of this and have setup a 'Valve Store' catering for this community offering them lots of Half-Life goodies to buy. The product range includes t-shirts, mousepads, posters and even Headcrab hats (seen to the right)! The store is not too expensive considering the merchandise sold are collectable items. The only downside is that the store is based in America. This means if you are unlucky enough to live in the UK or Europe you will find the products quite costly after shipping and tax. » Visit the Valve store
