New Re-Supply Gacha
The teaser shows R93's Live2D "Holiday Lucky Star" costume, which tells us that this is the same Costume Re-Supply Gacha as the CN 2019 Swimsuit Set.
All 6 costumes have been included below - Lewis's costume is a 2588 gem bundle while the other five are gacha. (*Gem pricing subject to change on EN release)
This is a point event that awards Serdyukov's "Black Crow Lifeguard" costume for free!
As usual, the event can be easily completed by players who actively play. Spending tokens for points is not required.
If you're not sure what a point event is, you can reference the below page for an example of a previous point event with the same mechanic.
The next major story event, Isomer, is finally coming to Girls' Frontline EN!
This will be the first event with both Easy and EX modes available for players to choose from, so new commanders can clear all of the story while veteran players can enjoy a challenge. (Clearing EX will also provide the rewards for Easy.)
As usual, a preparation guide by Ceia is available below:
For detailed ranking T-Doll recommendations, please check the Isomer Teambuilding Recommendations guide by Arcus.
True Core Mask
A True Core Mask is given as the clear reward for the Isomer campaign. It can be exchanged for any 5★ craftable T-Doll, so use it wisely!
If you're not sure whom to get, the same guide as the anniversary core mask applies (as the newest T-Doll batch is unlikely to have its T-Dolls available in the exchange shop).
Costume Package x2
Since these costumes were token gacha costumes on CN, we're not sure how much they will cost on release in EN. Hopefully, they'll be reasonably priced like the Anniversary bunny skins (~1280 gems).
Neural Upgrade * 5
Five new Neural Upgrades will be coming to GFL EN in July!
Judging from the preview, Micro Uzi's long-awaited Neural Upgrade will finally be available, just in time for Isomer! The other four T-Dolls are unknown at this time, but since MP-446 and Uzi are both getting a costume next month, MP-446's upgrade just might be around the corner too!
For more information on Uzi's upgrade, check out the detailed analysis written about it here. The below gif also sums it up pretty well:
