 * After August 6, 2010: Due to Feiris' D-mail 10 years into the past, Yukitaka Akiha lives, changing Akihabara from a mecca for otaku and moe culture into an electronics hub.

 * December 29, 2011: Okabe and Daru are kept under Rounder observation after being freed and sent back to Japan in order to not disturb the world line convergence.

0.337337α(Linear Bound Phenogram)

 * From the point of view of Suzuha.
 * This world line diverges a lot from the circumstances on how Suzuha fixes the time machine and how she discovers that Daru is her father.
 * Suzuha is hesitating over her priorities between her mission and friendship resulting in seeing ghosting figments of herself from the Beta and Omega? world line. Thus they refer to each other as Alpha, Beta and Omega.
 * While it is implied that Omega version of Suzuha is living a peaceful life with no knowledge of time travel. This conflicts with clues left from the first game (I'm beginning to wonder if Omega is really the negative number or if the negative number world lines are in a different attractor field. By the way, Omega Suzuha is a very spoiled kid)
 * Suzuha learns early on that Daru is her father due to Omega revealing it to her. Before going to 1975, Suzuha decides to spend some time with her dad Daru.

0.337199α (Linear Bound Phenogram)

 * August 10th, 2011 to August 11, 2011: Okabe become Alcapaman to solve many cases in Akibahara, with the help of "Mayuri". He settles cases to try to make sure Nae gets a game.
 * August 11th to 13th, 2011: Makise Kurisu returns from SERN. She has been working there for a year now. We find out that Okabe has been in denial for a year over Mayuri's death.
 * Okabe and Daru are freed early but are kept under observation by only Tennouji Yuugo and Kiryuu Moeka. (I don't know why he's back in Japan early and under little observation. He should have been released in December 2011 unless its a typo and he was released in December 2010)
 * Suzuha's time machine was confiscated, thus trapping Suzuha in 2010/2011. (This is a paradox I know. She should have been in 1975, but we have no clue what goes on in this world line).
 * Kurisu give Okabe an upgrade to the time leap machine. Her last resort to saving Mayuri. Okabe time leaps to a year ago to prevent Mayuri's death.

0.328403α(Linear Bound Phenogram)

 * From the point of Kurisu. Okabe is in distraught and broken mentally from the multiple time-leaps and failures to save Mayuri.
 * In this world line the one to find Okabe at the bridge is Faris and her butler Kuroki, not Kurisu.
 * Kurisu ends up getting advice from Yukata (Faris's father) and also manages to talk to her own father, Makise Souichi. After getting advice from multiple people, Kurisu resolves to time leap to save Okabe mentally and give him advice. At this point, this is the event where it ties into the original game.

0.000000α

 * Between 2033 and 2036: Kayano joins the Rounders and undergoes human experimentation in order to fortify her body.
