Short answer: Last Shelter: Survival updated almost every week in 2026.

Alliance events included Operation: Oblivion League All-Star and Clash of Alliances.

Long Tech Network ships small Last Shelter updates almost weekly. Most are fixes, but every few weeks one adds a hero, a growth module or an event. Every date and name here comes from the official App Store version history, which numbers 2026 versions as 26.xxx.

2026 update timeline

Heroes and growth

• Doomed Cowboy (May): a new SP hero, announced with the Doomsday Conquest Hero's Creed season and changes to faction heroes.
• Cube Energizer (August): a new growth module, with single-facet attribute display added a week later.
• Power rankings (August): new rankings for Mech Power, Arena, Pet Overall Power, Satellite Power and Super Aircraft Power, plus hero gear Might and Score leaderboards.
• Baneblade Tier 5 (June): a breakthrough tier was announced for the Baneblade.
• Legendary Flex Abilities (October): they can now be decomposed, so a wrong ability is no longer a dead end.

Events for alliances

Operation: Oblivion League 2026 All-Star started on May 18. Clash of Alliances All-Star Betting ran from June 5 to June 12 with doubled alliance rewards. Clash of Zones got its own icon in August. A City Trade season was tested in states 1421 to 1456 in March, and Bounty Hunter exchange rewards went up for seasons S3 and above.

Shop changes

A Boutique Treasure Voucher Exchange Shop was announced in May. In April the game added payment and delivery status notices for gifts, and group gift bundles were announced. In September gift pack purchases got a redirect screen. Many 2026 update notes also mention 500 Diamonds for updating, so check your mail after each update.

For spenders and alliance leaders

• Doomed Cowboy and faction heroes: if you build around SP heroes, plan hero items for Doomed Cowboy and check how the faction hero changes affect your current lineup before you spend.
• Cube Energizer is the newest sink. With rankings for mechs, pets, satellites and the Super Aircraft, check which ranking your server competes on and spend where it moves you up.
• Flex Abilities are safer now. Since decompose arrived in October, buying toward a Legendary Flex Ability carries less risk if you change plans.
• Leaders: All-Star events like Oblivion League and Clash of Alliances have fixed dates in the notes. Tell members to save speedups and healing for those windows. See the alliance leader page.
