: Maybe it started out with water, and then somebody added the ability to swim
: later? :)
Sounds familiar. :)
Doug designed “Ex Cathedra” before swimming had been implemented in Marathon 2, which served to illustrate the perils of making content for an unfinished engine. Doug described what happened:
“When I began this level, there was no swimming in the M2 engine and so the watery Grotto was filled with dead ends and traps, like underwater pits. To reach the key room that opened up the rest of the level, you had to make it past a series of jumps between ledges that you couldn’t see below the water - tricky stuff. Then swimming was enabled and suddenly the player could simply swim past the traps and tricks. There’s a secret door set in the wall of an underwater pit in the Grotto that was originally a big time-saver; after swimming, it was useless and I’m sure few people have found it.”
