Super Robot Wars/OG/Secrets

Note: While not secrets, something worth noting is that you can only get Lion F and SRX by playing Ryusei's route. You can also get an extra F-28 Messer on Ryusei's route. Also only on Ryusei's route, the Hagane is replaced by the Kurogane near the end of the game.

In additon, You can only get Kai Kitamura on your team by playing Kyosuke's route. Kyosuke's route also gives you an extra Gespenst Mk.II TT.

Both routes have five Gespenst Mk.II M. On Ryusei's route, you get three fairly early, and two more when the two routes combine. On Kyosuke's route, you get two at the beginning, and two more when the routes combine, but you will not get the fifth one until very late in the game, when Kai joins.
