About the Darwin's Soldiers Trope page on TV Tropes, I am trying to find some Shout Outs I can put in.
Let's see what I can remember...
(sorry, but there will be a lot more of my references than other people's)
===Video games===
The character of Ridley is named after a similar character from Metroid.
Shelton is disappointed at he lack of a [[HalfLife crowbar]] in the closet when raiding Raulson's lab.
The Phase Tank is modeled off the tank from Red Alert 2.
James mentions Silent Hill and Resident Evil at some point.
===Music===
The clearance question to auxiliary control references lyrics to "MacArthur Park."
"American Pie" by Don McLean is heard at the beginning of part 2 of
Card of Ten.
Vic says, "Ground Control to Major Roy," when testing Roy Hawkeye's radio in
Card Of Ten.
The password to the ADSA HQ is "Shave and a Haircut."
Like 30 songs are referenced as James and co. drove to various places in their cars.
===Historical Figures===
Darwin, duh.
The complete works of Shakespeare play an important role in
Card of Ten.
Shelton mentions Sacco, Venzetti, and Daniel Ellsberg when Hans asks about his chances at freedom.
Shelton himself takes his first and middle names from Rudyard Kipling and Oscar Wilde.
Many of the titles of works include famous names, like Schrodinger and Nietzsche. Others come from famous quotes, like [[WilliamShakespeare Card of Ten]] and [[{{Plato}} Ship of State]] (my upcoming story).
Lab 101 was named after Room 101 in George Orwell's
1984.
===Science===
The Einstein-Rosen Bridge is named after the hypothetical wormhole proposed by the eponymous names.
That chemistry joke I didn't get from the lab report in Raulson's lab. Might possibly double as an historical figures reference.
The Double Helix eatery.
Shelton mentions Kepler's Laws of Planetary Motion when describing how Gamas formed.
James uses the Coriolis Effect to select a corridor in
Pavlov's Checkmate.
Shelton also mentions having an Erdos number of 7 or 4, I forget which, in the first RP.
The Cobalt Squad in the first RP had a tendency to use famous scientists' names as derogatory terms directed toward the scientist characters, Examples of names used as such include Newton, Hawking, and Bill Nye.
Not really science, but James finds a CD encrypted in BASIC.
===Other===
Shout-outs to weaponry all over the freaking place.
Shelton says he feels like MacGyver when he gets himself out of a locked room.
Arnold Schwarzenegger is referenced when James blasts through the floor with a gun in
Card of Ten.
When Neku activates his lightsaber, Shelton warns him that it's not nearly as strong as the ones on ''Star Wars''.
Shelton's password to the computer system is ''killapp123'', both a reference to killer apps and Lotus-1-2-3, a spreadsheet program and early killer app.
Jessica Boyle of Escondido, a play mentioned in the first RP, is named after an actual person LB&T knew in real life.
The reference to Ender McThair in
Card of Ten established the anti-matter universe the characters were stuck in as synonymous with the Furtopia universe.
In
Pavlov's Checkmate, James uses "Nigel Munroe" as an alias, which happens to be the protagonist's name of a failed attempt to start a
Darwin's Soldiers RP in the Bulbagarden forums.
