Dread guides the player along an intended path for a first playthrough, but if you’ve ever seen speedruns there are quite a few different skips, and many of them are clearly developer-intended. There’s even a special easter egg if you skip Kraid to get Bombs and Phase Shift, then come back and use those on the boss.
It’s much more breakable than II, Fusion, Other M, and Samus Returns.

























This is a myth. You’re thinking of trademark genericization, but even that can only happen in very extreme cases.
