O really, i didnt read this until today:
ESCALATION
After his battle with the Master Chief during the New Phoenix Incident, the Didact fell into a slipspace rift generated by his flagship, Mantle's Approach, was transported Installation 03 (
Gamma Halo). Shortly after his arrival on the ring, he encountered Spartan Black Team, who was conducting classified reconnaissance operations on the Halo. Caught unprepared, the team was no match for the Didact, and all four Spartans were killed in the engagement. Soon after, the Didact was approached by 859 Static Carillon, monitor of the Composer's Forge. 859 had come to Installation 03 to investigate the activation of a service portal connecting the Halo to the Composer's Forge. Eventually, the Didact bargained with the monitor to gain access to the Composer's Forge so that he might assemble the Composers held there to strike back against humanity. Once again, the Didact was stopped by the Master Chief. However, this time the Master Chief found himself reunited with his fellow members of Blue Team,
Spartan-II's
Fred-104,
Kelly-087, and
Linda-058. Though their battle with the Didact was perilous and proved nearly fatal, the Spartans were able to band together, and with the help of 859 Static Carillion
they tricked the Didact into using the Composers on himself. Effectively turned into a digital essence, the Office of Naval Intelligence currently considers the Didact "contained", though it remains to be seen if his threat to humanity is truly at an end.
i know this is all known knowledge for people who read the comics/etc. But for me, having this on the website as general knowledge .... kinda funny lol.
After playing halo 4 mainline without other knowledge of comics/stories i would think the didact was dead. now if he just comes back ... as a digital essense aka AI? what in the F.. lol
