Mega Man Battle Network 4: Red Sun

Mega Man Battle Network 4 is a 2004 tactical role-playing game developed by Capcom for the Game Boy Advance (GBA) handheld game console. It is the fourth game in the Mega Man Battle Network series. The European version featured a completely different logo, which was also used on other Mega Man titles. Like Battle Network 3 before it, Battle Network 4 has two different versions, Red Sun and Blue Moon, that differ in story and gameplay details. Battle Network 4 is compatible with the e-Reader, and can be linked up with Rockman EXE 4.5 Real Operation and the Battle Chip Gate for NetBattles. It is able to link with Mega Man Zero 3, and contains references to Konami's Boktai series.
