What is Mantis-style? The objective of Mantis-style is to (currently) complete the Robot Master stages of Mega Man 1 - Mega Man 6 under the following rules:
1.) I cannot take damage from anything.
2.) I cannot use any weapon except the basic Mega Buster.
3.) I cannot use save states, except between bosses.
4.) I cannot miss a shot. Shots may also not be deflected by anything, unless it is part of the mechanic to destroy the enemy/boss.
Am I crazy? You decide.
