Mega Man Battle Network 5, known as Battle Network Rockman EXE 5 (バトルネットワーク ロックマンエグゼ5) in Japan, is a video game developed by Capcom for the Game Boy Advance (GBA) and Nintendo DS handheld game consoles. It it is the fifth game in the Mega Man Battle Network series, and the first Mega Man game to be released on the Nintendo DS. Battle Network 5 comes in three different versions: Mega Man Battle Network 5: Team Proto Man (ロックマンエグゼ5 チーム オブ ブルース Rockman EXE 5 Team of Blues) and Mega Man Battle Network 5: Team Colonel (ロックマンエグゼ5 チーム オブ カーネル Rockman EXE Team of Colonel), both for the Game Boy Advance, which have similar gameplay but slightly different supporting characters and stories, and Mega Man Battle Network 5: Double Team DS (ロックマンエグゼ5DS ツインリーダーズ Rockman EXE 5 DS Twin Leaders) for the Nintendo DS, which includes the content from both games as well as extra content.
Gameplay in Mega Man Battle Network 5 in this game is largely similar to that of its predecessors. The intrepid youngster Lan Hikari and his NetNavi (a sentient computer program) MegaMan.EXE must work to defeat the once-again-revived Nebula crime syndicate. Lan explores the real world and interacts with people and places there. When Lan jacks his PET, a handheld computer, into a computer with an interface jack (of which there are many), he can upload Mega Man to the cyber network. In that network, Mega Man can explore, but he's also threatened by viruses.
MegaMan battles viruses in Double Team DS.
When Mega Man encounters viruses (or, later, hostile NetNavis), the screen shifts to a battle screen, set on a six by three square grid. On the left half of the grid is Mega Man, and on the other half are his opponents. Mega Man has a relatively weak arm cannon, the MegaBuster, but his main weapon is Lan's library of battle chips, one-use-per-battle special attacks which grant various abilities, including simple attacks, defensive effects, terrain transmogrification, or assistance from other Navis. Before battle, the player can construct a folder consisted of thirty battle chips, and each turn of a battle (measured by a timer bar at the top of the screen), the player is presented with a random selection of these chips. The player can send Mega Man up to five battle chips, after which the battle takes place in real time, with MegaMan, controlled by the player, attacking with his MegaBuster, dodging attacks, or activating battle chips from his queue.
As implied by the games' titles, other Navis besides Mega Man play a much larger role. Mega Man joins a team led by either Lan's and Mega Man's rivals Chaud and ProtoMan.EXE or new characters Baryl and Colonel.EXE, and the members of this team assist MegaMan in various ways. Soul Unisons, originally introduced in Mega Man Battle Network 4 return: by using a chip of the right element to activate a Soul Unison (instead of its normal effects), Mega Man can take on the attributes of one of his teammates. For example, if Mega Man Soul Unisons with ProtoMan, his MegaBuster becomes a WideSwrd attack.
MegaMan uses his LongSwrd special ability in the second liberation mission in Team ProtoMan.
The team plays its largest role in Liberation missions. In Liberation missions, Mega Man and the rest of his team enter a part of the internet controlled by the Nebula crime syndicate, in order to free it from their control. Each Navi works autonomously, choosing corrupted Dark Panels to Liberate, or clear of Nebula's influence, to clear a path to the boss Navi controlling the area. Attempting to liberate a panel leads to a time-limited battle with a group of viruses. Each Navi has different abilities, including a unique chip always available to them in battle, a different weapon in place of the MegaBuster, and an out-of-battle ability which can clear multiple panels, protect teammates from damage, or other effects. These out-of-battle abilities almost always require Order Points, limiting their use. There is also a turn "goal" for each Liberation mission, with one turn representing the entire team of Navis attempting a liberation mission (or resting to restore HP). There are two Mega chips to be earned per liberation mission, one for completing the liberation mission on target or one turn less, and the better Mega chip for completing the liberation target in two or more turns less. Thus the player must actually complete each Liberation mission twice to earn both Mega Chips. Completing the liberation mission with more turns than the target will only earn zenny.
Also new to Mega Man Battle Network 5 are Dark Chips, super-powerful chips. While they appeared randomly in Mega Man Battle Network 4 when Mega Man was badly damaged, they are much more like normal battle chips in this game, in that they can be added to the battle chip folder like any other chip. Their extra power comes with a price: every time Mega Man uses a Dark Chip, he loses one point from his maximum hit points, permanently. He can, however, use a Dark Chip for a Soul Unison; this is called a Chaos Unison, which is like a normal Soul Unison except that his MegaBuster is replaced with the effects of the Dark Chip he used for the Chaos Unison. While using this effect doesn't cause HP loss, it has to be done with careful timing, as charging with poor timing causes the Chaos Unison to end and an invincible, evil version of Mega Man to join the viruses and attack Mega Man for a short period of time using random battlechips.
