*** ''Several'' Standard chips require you to S-Rank viruses in record time while using Custom Style and not using Navi chips or the buster.

* ObviousRulePatch: The ''Legacy Collection'' version disables Buster MAX mode during the postgame Time Trials to ensure the player faces the intended challenge.

* BalanceBuff:
** With the absence of the Fist series from ''Battle Network 2'', the Guts Punch series is expanded into three tiers and have their own command codes as well.
** The returning Styles had some of their abilities separated into Navicust programs that you earn from leveling them up, but they also gain a new unique ability to stand out.
*** Rapidly tapping B in Guts Style will unleash a burst of Buster fire, providing some firepower that offsets their poor fire speed.
*** [[JustFrameBonus A well-timed blocking]] of an attack in Shield Style will restore some of your HP.
*** S-ranking certain viruses within five seconds in Custom Style without using the buster or Navi Chips will yield a unique chip from them.
*** S-ranking bosses in under twenty seconds in Team Style yields a V4 variant of their Navi Chip.

* BalanceBuff: With the absence of the Fist series from ''Battle Network 2'', the Guts Punch series is expanded into three tiers and have their own command codes as well.

* EarlyInstallmentWeirdness: Introduced in the game is the Omega-level Navis (SP in Japan), which is a stronger fourth-tier form. While later games just treat them as the third form in practice, here they require certain degree of completion to unlock and their boss battles were preceded with a 3-round virus gauntlet. They are also set encounters like their Alpha/V2 forms, though their locations are unknown without a guide.

** The penultimate chapter has [=MegaMan=] fight his way through the Undernet's ranking system to meet their leader "S", who holds the Forbidden Program that is the only thing that can stop Alpha. This means tracking down numerous Navis around the net and defeating them until you can meet S and claim the program. But then the Forbidden Program is rendered useless when, in a ContrivedCoincidence, Bass is immune to its power and {{No Sell}}s it and escapes with Alpha; come the endgame, [[ShaggyDogStory Alpha is destroyed without the need for the Forbidden Program anyway]].

* YouCouldHaveUsedYourPowersForGood: In the ending, [[spoiler:a data version of Tadashi Hikari]] respects Dr. Wily's abilities as a scientist while lamenting his FaceHeelTurn. This is justified because they worked on the Soulnet together, so he knew what Wily would be capable of if he used his skills for good.

** Bass is constantly protected by an Aura that only disappears when he recieves enough damage in a single hit. Players must either figure out a good way to destroy it before [[AlphaStrike piling on as much damage to him as possible before he can regenerate it]], or figure out Aura's mechanics and damage that can ignore it (ex. poison). Harder versions of his fight use an even stronger version of aura.

*** V4 Navi Chips can only be obtained if you S-Rank bosses under 20 seconds while using Team Style. You're not told about these until you've obtained and chose to keep these Styles yourself, and if you currently lack either when you need to complete a library, it's back to grinding Styles until you get the right one.

** Some jack-in ports [[AlwaysCheckBehindTheChair weren't as obvious to find from the player's view]].

*** Some others, such as the Lion Comp, are locked behind story progression and give no indication of being able to be jacked into.
