The ASTD X Summer Event update delivers one of the biggest content waves of the year, introducing new game modes, exclusive units, fresh event shops, and a lineup of valuable rewards for both solo and team players.

What is the ASTD X Summer Event Update?
The ASTD X Summer Event update is packed with new activities and unique opportunities for every player. At the core of the update is the new 6-player Summer Raid, where enemy elements rotate every 4 hours, offering a constantly changing challenge.

How to Get Firework & Event Rewards
During the Summer Event, Firework tokens can be earned by playing stages or raids. These tokens are limited and can be exchanged for rare units in the event shop—however, once the total supply (20,000) runs out, they’re gone for good. Summer Shop coins, meanwhile, are collected from event activities and used for time-limited items and upgrades.
Event Participation Tips:
-
Play Summer Raids as often as possible for a chance at all major rewards.
-
Check in with the NPC Old Man on the Bench to track your Pirates vs Marines progress.
-
Use your Firework and Summer Shop coins early, as supplies and shop availability are limited to the event period.
