The game, the soundtrack, and have your name appear in a hidden level
The game, the soundtrack, and - record yourself screaming out some (family friendly) last words (about 2 seconds long), and we'll include them as part of the sound effect when Cthulhu steps on a building in Modern Earth... (extra points for hilarity!)

The game, the soundtrack - plus send me a picture of you pulling your most horrible face (...or your passport photo...), and it'll appear in-game in the 'Lost and Hidden Shrine to Those Horrors That It Is Better To Die Than To Glimpse... Even For A Second...' Easter Egg.
All of the above, plus send me a few pictures of your house and I'll make it a squish-able, last-words-screaming object in the final level.
All of the above, PLUS get mentioned in the credits, PLUS have your name appear as a key part of the terrain of a hidden level, PLUS eternal gratitude, admiration, and just a little bit of fear...
