Singularity/Fridge

Fridge Brilliance

 * Okay, so having an E99-armed Soviet Union curbstomp the world in the 1960s without anyone coming up with any deterrents is implausible, right? It seems like it...until you realize that not only is the USSR's new power coming from a line of research that no one else in the 1950s has imagined, let alone done basic theoretical work in, but said research has literally given the Soviet Union time machines. If a defector steals some samples or someone at Los Alamos starts making independent discoveries, Moscow can just send someone back in time to kill them before they've done any damage. And they can do this as many times as they want.
 * Hey, why is the pathfinding function made out of footprints?.
 * The explosion at the Singularity that wrecked the island and spread E99 radiation everywhere is.
 * To clarify:.
 * Why does the description for the futuristic-looking assault rifle say it's built
 * Additionally, the Valkyrie is very clearly modeled on the AK-47, which not only parallels how Russian rifles have evolved in reality, but explains why you can find ammo for it in 1955.
 * Why do the Phase Ticks, when mutated and inflated with the TMD's de-aging function, begin to attack their own kin? Why, it's the same with humans: Reverts are universally aggressive toward all humans as well.
 * Here's something that will only become apparent upon multiple playthroughs: Those hidden messages scrawled in E99 dust that you reveal with the TMD? On a replay, the ones you have uncovered will remain uncovered, and any you haven't yet found will remain obscured.
 * Furthermore
 * This troper had a moment of boredom near the end of the game. Specifically, immediately after putting one between Demechev's eyebrows, and figure he could just take potshots at the good professor. Then he fell over, dead. Did not see that coming.

Fridge Horror

 * The island is called "Katorga 12." The "Katorga" was a system of penal colonies. How many of the people working on the island were actually volunteers?
 * It was a penal colony during the '40s, when they were mining for Uranium (a job usually delegated first and foremost to those people you wouldn't miss). When they found E-99 and set up the facilities, it's pretty clear that everyone was enthusiastic with the project, and their families were there as well.
 * On a vastly more massive scale,
 * It's revealed at the end that all the faded notes written on the walls were written by
 * Why is the Russian spoken by enemy soldiers so painfully bad at times? Because it's Soviet Union! A multilanugaged country with obligatory Russian in schools, yet not known for teaching languages well. They may be Baltic.
