Super Robot Wars Operation Extend

Super Robot Wars Operation Extend (OE) is a Play Station Portable title that was released July 18, 2013. It is a mostly DLC only game, only shipping a game disc with most of the base game assets, and the 8 game chapters, additional mission packs and extra units and bonuses must be purchased via the Playstation Network.

It reuses the game engine from Super Robot Wars NEO, in a modified form, and features many classic series, newer series, and some truly oddball entries like Keroro Gunsou.

 * Adaptation Distillation: Used in an unorthodox manner. For starters, since most of the characters were taken from their canon universes at certain points in time, that means most of the storylines from the universe were essentially thrown out to some greater or lesser degree.
 * Gurren Lagann has Kamina, Simon, Boota, and Yoko in the Gurren Lagann as pilots, so it's obviously set before, and since Viral shows up, that means they were pulled out of their world from around Episode 3, though most of the attacks used by the Gurren Lagann wouldn't debut until later episodes, since as the Throne Break MAP attack.
 * Code Geass has Lelouch and C.C in the Gawain, and Suzaku, Lloyd, and Cecile with the Lancelot, meaning the earliest they could have shown up in the OE world is shortly after Zero hijacked the Gawain.
 * Da Cider and Lamune are allies and the debut scene shows Lamune back in his world, so their series has already concluded. Ryu Knight has also concluded it's series as well by the start of the game.
 * Shin Mazinger shows up with the Jet Scrander, so it was taken from the series midpoint.
 * Only the Wing Zero Custom and GN Exia Reborn with Heero Yuy and Setsuna F. Seiei show up at first, and since the Endless Waltz Wing Zero does not appear, Heero has arrived from sometime during the TV series (at least before the fight Zechs and he have in the Antarctic) and Setsuna after Gundam 00 S2. Zech Merquise/Millardo Peacecraft later shows up with the Tallgeese, confirming TV series Gundam Wing is used, and Graham Aker from Season 2 of Gundam 00 shows up as well.
 * Gundam is snarled together in an odd manner. The original series One Year War never properly concludes due to the events caused by the invading Mucus, and the events of Gundam 0083 never occur, so the Titans from Zeta Gundam do not exist. Incidents like the 30 Bunch G-3 poison gas still happen, but Zeon is responsible. The 08th MS Team have a compressed version of their own series folded into the original Gundam plot, with Ginias Saharin in the Apsaulus III being part of the Zeon strike force on . The Solar Ray incident is also averted.
 * Ascended Fanboy: In universe, Keroro is a big fan of Gundam models in his own series. In this game, not only does he get to fight alongside Gundams of all types, he can even pilot his own copy of the Rx-78-2 Gundam courtesy of some DLC.
 * Bribing Your Way to Victory: You literally have to pay for over 95% of the game. Some of it is useless padding, but a lot of it does give you in-game money and items to make the game easier.
 * DLC: To a ridiculous degree. The entire game past the prologue has to be downloaded.
 * Continuity Nod: Much like the series they were from, both Zero and Suzaku wind up on opposite sides yet again, for highly similar reasons. For bonus points, Zero himself is helping out the heroes, while Suzaku joins the villains (while believing them to be otherwise).
 * Fish Out of Water: Over 3/4th of the cast fall into this, quite literally, as they more or less fall into the OE universe from their own.
 * Loads and Loads of Characters: An intentional goal of the game is to add as much of this trope as possible.
 * Lazy Artist: While a lot of new art, music, and sound effects were created, the game uses the stock assets of SRW NEO and GC/XO as a base. Even some of the DLC content does this, with the Cybuster DLC using stock assets for the music, sound effects, and even the face portraits from earlier games, only adding in a new 3D model and animations, and "PG Gundam" DLC just adds new voiceovers and face portraits for Keroro, who is otherwise using stock game assets to pilot a clone of the RX-78-2 Gundam. Face portraits for some characters like Kamille are even blatantly lifted from older games.
 * Padding: Used quite a bit to pad out the game length, with some missions being totally nonessential to game completion, and some are just DLC content that never need be played, as they don't add any story or actual game content.
 * Post Script Season: A few series have already had their plots concluded by the start of the game.
 * Ragtag Band of Misfits: While this trope is already used extensively in the series as whole, this game puts a unique spin on the concept by combining it with the Fish Out of Water trope. In short, over 3/4ths of the cast is removed from their own universes and forced to band together to survive.
 * Spiritual Successor: In part to SRW GC/XO and the Z series.
 * Unfortunate Name: The original enemies are named Mucus. As in, you know, snot.
 * Zerg Rush: Though multiple enemies are compressed into squad units, it's not uncommon to have some stages filled with enemies who will all try to gang up on your team.
