Link with Mega Man Battle Network 4[edit]
Mega Man Zero 3 can be linked with Mega Man Battle Network 4 (either Blue Moon or Red Sun). If you move any one MMBN chip to Mega Man Zero 3, the enemies in cyber-space will change permanently: most of MMZ enemies will be replaced by MMBN enemies.
Mini-Games, Hard Mode and Ultimate Mode[edit]
There are 9 unlockables in the game: 2 modes and 7 mini-games. It is possible to unlock them all playing through the game just 7 times.
The Ultimate Mode (easy mode) was already available in Mega Man Zero 1 and 2, but it was just a reward, instead of a new challenge. In Mega Man Zero 3, on the contrary, the introduction of unlockable mini-games is a challenge to be met specifically with the Ultimate Mode. Modification Cards might be allowed in Mega Man Zero Collection.
