Rockman 4: Minus Infinity


A hack of the original Rockman 4 with new levels, bosses, and weapons.

Rockman 4 Minus Infinity (Rockman 4−∞, ロックマン4−∞, ロックマン フォー マイナス 無限大) is an excellent Mega Man 4 ROM hack by Japanese ROM hacker Puresabe

The levels, bosses, weapons and even the choice of music of the original Rockman 4 have been improved to a level that far exceeds an aesthetic standpoint – bosses have new attack patterns, weapons and moves (such as the distinguishable ‘desperation’ moves that speed up the music and make the bosses angrier and faster).

The levels have branching pathways and hidden bosses from past Mega Man/Rockman games that won’t fail to put a smile on your face (such as Shadowman robbing the Egyptian temple, or Crashman hiding in the weapons artillery of Drillman’s stage), the music is very well chosen from a variety of different games, and new enemies from earlier and later games in the franchise, not found in the original Rockman 4, make an already fantastic piece of programming a platforming masterpiece.

Give it a try, you won’t be disappointed…
