Summer Lane: What to Prioritize Before It Ends

MONGIL: STAR DIVE Summer Lane (Version 1.2 seasonal map) priority route: login gifts, festival missions, and claim order before the announced July 28, 2026 close. Treat the in-game timer as final; use this as an archive checklist if the event has ended on your account.

Direct answer

Summer Lane is the limited-time seasonal map added in the Version 1.2 summer update. It is open now and announced to close on July 28, 2026; the in-game client timer shows the exact time for your region. Open the Summer Lane map, check which Grand Summer Festival Missions are still reachable, and claim every completed reward before the timer ends. Permanent systems like Dispatch can wait.

Use the client timer as the final deadline

Netmarble announced that An Unforgettable First Summer Dive runs through July 28 and takes place in Summer Lane. The live client is the final authority for the exact closing time in your region.

Finish time-limited work before permanent systems so completed event rewards do not get left behind.

Open the event screen and record the remaining time shown in the client.
Enter Summer Lane once so you can see which attractions and missions are still available.
Claim the current Summer Special 7-Day Gift if it is available on your account.
Complete only the Grand Summer Festival Missions you can still reach before the timer ends.
Claim every completed reward before leaving the event screen.

What can wait

Dispatch, Monsterling trait management, and the added Conquest difficulties are Version 1.2 systems without the July 28 event deadline in Netmarble's announcement.

Check them after the limited event actions. Do not spend premium currency or upgrade materials solely because a checklist says a reward is important; compare the reward in your own client first.
