Rockman EXE 4 - Tournament Red Sun (Japan) (Rev 1)

Released in 2003 by Capcom for the Game Boy Advance, Rockman EXE 4 - Tournament Red Sun (Japan) (Rev 1) is the fourth mainline entry in the beloved Rockman EXE (Mega Man Battle Network) series, and the counterpart to the simultaneous Tournament Blue Moon release. This revised Rev 1 version fixes minor glitches and balance issues found in the original Japanese launch, delivering a smoother gameplay experience for retro fans. The game picks up after the events of Rockman EXE 3, following protagonist Lan Hikari and his NetNavi MegaMan.EXE as they enter the new World Three NetBattle Tournament, a global competition that draws the best Navi operators from across Japan. Unlike earlier entries, Rockman EXE 4 introduced dynamic story branching that changes based on your in-game choices, with Red Sun featuring exclusive story beats, boss encounters, and rare Battle Chips not available in the paired Blue Moon version. The core blend of real-time action and tactical deck-building that defined the

Game Guide

Rockman EXE 4 - Tournament Red Sun (Japan) (Rev 1) blends tactical deck-building and fast-paced real-time combat, so mastering core fundamentals will help you dominate the tournament and beat tough late-game bosses. Start by keeping your Battle Chip deck small: stick to 20-30 chips total to increase your odds of drawing your most powerful moves in every match, instead of clogging your deck with low-value filler chips. As a Red Sun player, you have exclusive access to ProtoMan-focused story content and rare Red Sun-aligned Battle Chips, so complete early side quests in ACDC Network and YumLand to unlock these unique tools as soon as possible. When facing tournament bosses, always check their element alignment: fire chips deal double damage to grass-type Navis, electric chips stun water-type opponents to stop their big attacks, and wood chips bypass certain shield defenses common in late-game fights. This Rev 1 revision adjusted balance from the original Japanese launch, so old overpowered chip combos from the unpatched version are nerfed—avoid relying on those outdated strategies, and instead mix fast attack chips with support chips for flexible play. If you struggle with the final tournament boss, add the UnderShield support chip to your deck to block one-hit KO moves, and pair it with quick sword chips to wear down their high health over time. Farm the Undernet early to get rare *-code chips that work in any deck, regardless of your Navi’s code, and complete daily fog-clearing events to unlock hidden rare chips and customizer parts that permanently boost MegaMan.EXE’s stats for post-game challenges.
