This is both an Exploration and an improvement hack, with features such as beam stacking, weapon and enemy damage tables, and items added after boss defeats, in addition to a very new map. I believe it is harder than vanilla Metroid, but more rewarding, despite the lack of a functioning Tourian (the data is all there, but has problems that I don't have time to learn how to fix).

See my Forum thread for more information about this hack.

After some recent problems during testing, I've slowed Samus down a little and created a second ips with the slower speed. It's still faster than the original, but the door transition problems I was having with the original have now been fixed.
