1. Added a Quick Install Chips feature to Galaxy Arena. You can now automatically install the highest-level available Chips into all empty slots with a single tap. 2. Made minor performance improvements to the calculations for Ball Lightning, Waterdrop, and Chain Lightning. 3. Optimized the auto-targeting logic when both a Boss and an Elite enemy are present. Sentinels will now prioritize attacking the Boss. 4. Fixed an issue where the Laser Vulnerability text was not displayed correctly.

User reviews

Don’t bother

Not a very good game, lifetime removal of ads cost 80$ Yes, think it through, 80$, not the price of a cup of coffee. Not that this game would’ve been worth buying even for 4$ mind you

!!! STOP PUB !!!

Un jeu qui démarre dès la première minute sur de la publicité façon IOI ? Non merci ! Pas pour moi ! Je passe donc mon chemin !

Hot iphone

My iPhone 12 is getting really hot. Is it possible to make the graphics settings even less demanding? (The settings are already at their lowest.)

Binary star 20 impossible

Binary star stage 20, they made it disgustingly difficult to pass. You’re wrung in long enough that you like the game and need to spend money to continue. You can fly through levels until you get to 20. Then you’ll be stuck for 2 weeks with no progress unless you spend $50-$60 worth of upgrades. Play till 20, then uninstall.

Scammed

Decided to purchase the $5.40 frontline supply honor pass , there’s a check next to my purchase but all the rewards are locked …….. it’s like I payed for nothing …. This was a fun but this is why I’ll never spend money on phone games. Thanks for scamming me like this . Very unfortunate
