There’s more to do in Tactics Ogre: Let Us Cling Together after you decide Denam’s fate. Square Enix has downloadable scenarios planned for the PSP version.
Canopus and Denam are the central characters in the first extra storyline, The Search for Warren. Even though anyone can download the mission, you have to meet certain conditions to play it. The Search for Warren will be available via PlayStation Network sometime in December.
Two more downloadable scenarios are in the cards, but Square Enix have not released any details about them.
