Well, the point of this presentation will likely be a talk into the development process of each map and advice on developing similar games. Stuff like mapping, balancing, coding, etc. Nothing too interesting unless you're a budding developer.

The stuff about there being more undiscovered easter eggs is Der Reise is probably bull, to be brutally honest - anything major would've been found in the game files. Literally every square inch of that map has been inspected by the community.
