Destructoid - Some of the most fun I've ever had playing videogames has been with the Half-Life series. The games are most famous for their scripted sequences, but there are a lot of other clever pieces of design in them. Today, I'm going to look at a bunch of great Half-Life setpieces all themed around one entity: the barnacle.
The barnacle can do horror, action, and even comedy. It can assist you and puzzle you. To do all that, an object needs to have some pretty fundamental stuff in its design.
