The second entry of the Wonderswan series of Super Robot Wars, the Super Robot Wars Compact 2 story was so big it had to be separated into three parts: Earth Crisis, Cosmoquake and Galaxy Showdown. The story deals with the battle between Earth's forces and the extraterrestrial Einst, who seek to restart the world they deem too corrupted. The key to Einst's success or defeat lies within two cadets in the Earth Federation's forces, serving as the game's Original Generation.Arguably one of the more famous SRW entries, despite the obscure handheld system it started out on. It was later remade using the Super Robot Wars Alpha Gaiden engine as Super Robot Wars Impact, the series' first entry on the Sony PlayStation 2, with all three games compiled onto one disc. In addition to introducing a new original character named Einst Alfimi, Impact adds two new series to the game: G Gundam and Martian Successor Nadesico. Like the preceding Super Robot Wars Compact, Compact 2 and Impact features the "Free Route System": rather than following a linear plot, the games allow the player to choose the order to play certain scenarios in. This may affect the storyline or give the player an opportunity to unlock hidden units and/or characters.
Series included in the Super Robot Wars Compact 2 trilogy/Impact (debuts are in bold)
Badass Normal: While most of his other companions are pilots with powerful psychic abilities or pilots who pilot Super Robots (Kouji, Tetsuya, Duke, Getter Robo Team, Akira, Combattler V Team, Rom, Domon, the Zambot 3 Team, Banjou) a Kyousuke manages to kick-ass & win battles solely by his insane skills & crazy amount of battle experience behind the cockpit(He IS the only person that can pilot the Alt Eisen/Alt Eisen Riese.) The only thing thats abnormal about him is his insane luck giving him the capability to survive injuries that can kill any other man/woman.
G Gundam Combination Attacks: Double God Finger (performed by God Gundam and Nobel Gundam), Double Sekiha Tenkyoken (performed by God Gundam and Master Gundam) and Love Love Finger (performed by God Gundam and Shining Gundam)
Machine Robo Combination Attacks: Double Kamaitachi (performed by Vaikungfu and Blue Jet) and Inazuma Cyclone Ganban Wari (performed by Vaikungfu and Road Drill)
Martian Successor Nadesico Combination Attacks: Buttercup Formation (performed by Aestivalis-Ryoko, Aestivalis-Hikaru, and Aestivalis-Izumi) and Double Gekigan Flare (performed by Aestivalis-Akito and Aestivalis-Gai)
Gratuitous German (The names of Kyosuke and Excellen's mecha; similarly, all the names and attacks of Einst units and characters)
Guys Smash, Girls Shoot: Kyosuke's Alteisen is a massively armored mech whose main weapons are a stake driver and a pair of humongous claymores. By comparison, Excellen's Weissritter is a speedy, lightly-armored machine armed with a large rifle.
Hard-Drinking Party Girl, with a mix of The Pollyanna: Excellen loves her alcohol, but she doesn't need it to become the latter: it's part of her nature, because her sunny disposition is what really cheers the cast up during the downer moments.
Improbable Weapon User (Kyosuke's Alt Eisen uses a pile bunker and mecha-sized titanium ball bearings as weapons. When it's upgraded to the Riese, it can't even move with the extra armor: who in the right mind would want to use this machine?? Fortunately, he's the only one who can ever use it and factor in his ungodly luck, here's a true example of a weapon not fit for anyone but him)
Also slightly played at the same time: Excellen only ever calls it the "Love Love Attack"
The original attack even shows up. The only difference is that Rain pilots the Shining Gundam for Impact.
Put on a Bus (The only characters from G Gundam brought over for Impact are Allenby Beardsley, Domon Kasshu, Dr. Kasshu, Dr. Mikamura, Kyoji Kasshu, Rain Mikamura, Schwarz Bruder, Master Asia and Ulube Ishikawa)
