it is less about overpowering the opposing forces and instead about maintaining position control and sacrificing units to gain a larger advantage. Similar to FTL, the game is broken into a sequence of islands each with a number of scenarios (based on island sectors) to complete; while the islands remain the same each game, the scenarios themselves are generated procedurally in a roguelike manner. After completing the first island, the player is given the choice of which islands in the sequence to protect next; islands have various conditions that can affect combat scenarios, and more hazardous conditions can gain greater rewards from completing the scenarios on each. Should the player lose any scenario, either due to their 3 mechs becoming disabled, losing their power grid, or failing to protect a specific target for that scenario, then the player has the option to send one of the pilots back in time prior to the start of the first mission – effectively starting a new game – retaining their current experience and abilities to give an edge in the next battle. Reviewers for the website Rock Paper Shotgun described the gameplay as a mix of Pacific Rim and Edge of Tomorrow due to the time-traveling elements. Other permanent improvements, such as new pilots or sets of mechs, become available as the player completes various milestones. Development Into the Breach came out of ideas that Ma and Davis had following the success of FTL. They had tried various prototypes for a game, including one for a grid-based tactical system, which they recognized was seeing a resurgence in the video game industry due to the success of XCOM: Enemy Unknown (2012). However, they still needed some type of hook to differentiate their game. This came as a response to films like Man of Steel and Pacific Rim, where "the whole city gets demolished, but no one cares because the good guys won", according to Ma. They set about to make the game focus on the impact of collateral damage so that defending buildings and other structures would become a priority rather than just winning. Subset included the effects of giant mechs-vs-giant alien battles on the landscape as the game time progress, with mountains being torn down, forests destroyed by fire, and buildings razed. To emphasize this in gameplay, they include the mechanic that mechs are powered from local power nodes in the buildings, so
