Mega Man Battle Network 4: Blue Moon vs Rockman EXE 4.5: Real Operation
Side-by-side comparison of features, pricing, ratings, and alternatives.


Step back into the cyberworld with Mega Man Battle Network 4: Blue Moon, the fourth major installment in Capcom's beloved tactical RPG series. Players follow Lan and his NetNavi partner Mega Man.exe as they navigate real-world adventures and dive into interconnected computer networks to battle malicious viruses. This version introduces a unique tournament-focused storyline where players must defeat various rivals to progress, alongside the innovative Soul Unison system that allows Mega Man to harness the power of defeated foes. Combining real-time tactical combat with deep deck-building mechanics via battle chips, Blue Moon offers distinct enemies, chips, and transformations compared to its counterpart.
Rockman EXE 4.5: Real Operation is a spin-off of the Mega Man Battle Network series released exclusively in Japan. Acting as a NetNavi simulator, the game shifts the core gameplay so that NetNavis are controlled by AI, while players participate by 'slotting-in' BattleChips and issuing strategic commands. The game was originally designed to integrate with physical BattleChip toys and the BattleChip Gate accessory, enhancing the authentic Operator experience. It features a wide selection of playable NetNavis, including MegaMan.EXE and the twelve Navis that contribute DoubleSouls in Mega Man Battle Network 4, accompanied by classic stage theme remixes.
