Spekter Agency: Survivor (official site)’s version 1.5.0 update adds Monster Wave, a new survival mode where Agents hold off waves of incoming enemies, upgrade their skills and compete for leaderboard spots. The patch also raises the Normal Stage cap to Stage 140 and the Abyss to Floor 1,400. It brings two new Boss Match bosses, a cherry blossom event built around Vel, and new shop and VIP options.
Monster Wave
In Monster Wave you survive an endless assault of monsters for as long as you can, upgrading skills as you go and chasing a place on the leaderboard. The mode plays differently from the rest of the game, so the update removes the Experience Range and EXP Gain Efficiency options and replaces them with Skill Card Drop Cooldown Reduction. With that option, Agents pick up Skill Cards faster during a survival run.
Playing the mode also pays out extra rewards based on how many times you enter. You can claim participation rewards up to twice per day.
Monster Wave Fund
The Monster Wave Fund launches alongside the mode and rewards you for playing it. Each completed Monster Wave attempt adds progress toward more Fund rewards. It has a free reward track and a premium one.
Stage 140 and Abyss Floor 1,400
Version 1.5.0 lifts the limits on both Normal Stages and the Abyss. The new top end is Stage 140 and Abyss Floor 1,400, with harder encounters aimed at experienced Agents who want to push their builds further.
Vel’s cherry blossom event
A Vel event runs from November 10 to November 24, 2026. It’s cherry blossom themed, with special rewards, event currencies and a limited-time Bell Shop. When the main event ends on November 24, the event Gacha and the Bell Shop stay open for another 7 days, so players have a week to spend leftover event currency and claim rewards.
New Boss Match bosses
DRAKULL and GARGON join CHUBRAGON in Boss Match. The mode now rotates its boss every week, so Agents face a different fight from one week to the next.
Shop and VIP changes
The update opens a Super Deal Shop with limited-time packages for upgrading selected abilities to Epic rarity. Each package costs $0.99, and each account can buy each package once.
The VIP Card lineup is growing too. The Ad Removal Card now has a permanent option alongside the existing 30-day one. There is also a new 30-day Monster Wave Card for players who spend a lot of time in the new mode. It adds convenience features and daily rewards for Monster Wave attempts and leaderboard pushes.
