KetoprakDL – Sol Trigger (Japanese: ソールトリガー) is a role-playing video game developed by Image Epoch for the PlayStation Portable. It was released in Japan on October 4, 2012.
The game is a turn based RPG. It features gameplay mechanics such as “Sol System”, where the players can activate characters’ “Sol Power” to activate special moves that become stronger the more they are used. “Sol Power” can also be traded away in order to revive teammates in battle as well, similar to the game Soul Sacrifice. Additional skills can be learned by equipping new weapons.
The game is set in a distant future, based around the fictional city “Kaiserhald”. In the game’s world, “Sol” has the power to create miracles, but is hoarded by Kaiserhald and its “Machine Church”. The “Sol Trigger” is a group of people who oppose their corrupt use of the “Sol”, and they fight to stop them.
