Space Imperia 4X — Patch 0.1537

Patch 0.1537 for Space Imperia 4X introduces new combat options for Cloaked Raiders, allowing them to avoid combat and includes a toggle for this behavior. Combat resolution now lets the attacker choose which battle to resolve first, and various group management bugs during combat have been fixed, such as issues with merging, splitting, and firing sequences. Doomsday Machine behaviors have been adjusted, including attacker identification, movement, and damage retention across battles. Several quality-of-life improvements address UI responsiveness, ship selection, and warning displays, while multiplayer fixes resolve timers, calculation discrepancies, and shot playback errors. Additionally, solo mode updates modify alien fleet and Doomsday Machine interactions to align more closely with intended mechanics.
