You just gave me an idea ! <| sep |> Not sure they will go back down to 50 . That ' s 450 k for the set , and the cards are selling for quite a bit more than that . <| sep |> The knee is down , or at least there is no clear evidence that it isn ' t , so the lions should keep the ball . <| sep |> Using contactors you can put as many light as you need on a photocell <| sep |> Check out Hillside , SubTheWub , and Doom 2 Entryway for some examples of these types of maps . Hillside and SubTheWub are probably not what you ' re after as playing them in multiplayer pretty much trivializes the game but they are very challenging single player maps but Doom 2 is a good example of what you ' re after . <| sep |> I personally didn ' t understand the movie at all as a kid , maybe i should rewatch it
