City 17 Half-Life 2
This Eastern European city is under the control of the Combine, who love marching into people’s houses with guns, and broadcasting propaganda on big television screens. Venture out of the surveillance state-y city centre, though, and City 17 looks like it could use a good hosing down with chemical cleaning fluid. Barnacles – Half-Life’s enemy type which grabs onto you with its tongue, pull you towards it, then bites you until death – are all over the place. If you haven’t got a crowbar handy, the whole thing is rather scary, and you’re better off just staying put in the city and trying not to get whacked on the head by an angry Combine guard.
