Spekter Agency: Survivor (official site) has released version 1.5.0, and the headline addition is Monster Wave. It’s a new survival mode where Agents fight off waves of incoming enemies, upgrade their skills along the way and compete for spots on a leaderboard. The update also pushes the Normal Stage cap up to Stage 140 and the Abyss up to Floor 1,400. Two new bosses arrive in Boss Match, Vel gets a cherry blossom event, and the shop and VIP lineup pick up new options.
Monster Wave
Monster Wave asks you to last as long as you can against a monster assault that never ends. You upgrade skills during the run and aim for a leaderboard placement. Because the mode doesn’t play like the rest of the game, the update drops the Experience Range and EXP Gain Efficiency options and swaps in Skill Card Drop Cooldown Reduction, which lets Agents collect Skill Cards faster in a survival run.
You also earn extra rewards tied to how many times you enter the mode. Participation rewards can be claimed up to twice a day.
Monster Wave Fund
A Monster Wave Fund launches with the mode and pays out for playing it. Every Monster Wave attempt you complete adds progress toward further Fund rewards. There’s a free reward track and a premium track.
Stage 140 and Abyss Floor 1,400
The caps on Normal Stages and the Abyss both go up in version 1.5.0. Stage 140 and Abyss Floor 1,400 are now the highest points, and the tougher encounters there are meant for experienced Agents looking to take their builds further.
Vel’s cherry blossom event
From November 10 to November 24, 2026, a cherry blossom themed event built around Vel is live. It includes special rewards, event currencies and a limited-time Bell Shop. The main event wraps up on November 24, but the event Gacha and Bell Shop stay open for 7 more days, which gives players a week to use any remaining event currency and collect rewards.
New Boss Match bosses
Boss Match adds DRAKULL and GARGON next to CHUBRAGON. The boss now changes every week, so Agents get a different fight each week.
Shop and VIP changes
A new Super Deal Shop sells limited-time packages that upgrade selected abilities to Epic rarity. Every package is $0.99, and each account can buy a given package once.
More VIP Cards are on offer as well. The Ad Removal Card can now be bought as a permanent option, in addition to the 30-day version that was already available. A new 30-day Monster Wave Card is aimed at players who spend a lot of time in the new mode, with convenience features and daily rewards for Monster Wave attempts and leaderboard pushes.
