Squad Busters x Sonic update: Release date and new Heroes

According to the official Squad Update video, the next Squad Update will arrive on June 17, 2025, with two new Heroes, new Squaddies, and more. Furthermore, the developer promised that players will get permanent characters from the Squad Busters x Sonic the Hedgehog collaboration in this update.

Two new Heroes will show up in the upcoming update — Sonic, the speedster hero, and Spike, the healer hero. Squad Busters 2.0 update promised one Hero for every Hero Class. With the inclusion of these two new Heroes, that promise will be fulfilled.

Check out details about the new Heroes below:

• Sonic: Sonic will be a speedster hero who will turn into Super Sonic when you trigger his power. The Super Sonic form will make him invincible for a few seconds while boosting the squad's movement speed while active. His passive Trait helps charge Super Sonic 20% faster when using Turbo. When upgraded, Sonic's Trait helps boost the attack and health of the speedster Squaddies in his team.
• Spike: While the developer did not share details about how to unlock Spike, their first Healer Hero, they shared certain sneak peeks of his power and passive Traits. From the video, it seems like Spike will throw Spike Bombs towards the enemy squads to stun them briefly while knocking them airborne. His passive Trait at level one will provide Healer Squaddies 15% extra Health and 15% extra Attack Speed. So we can expect that upgrading his Trait will provide similar buffs to the Squaddies. Spike will not be a part of this update, but he will arrive in the game during the Summer of 2025, as confirmed by Paula in the video.

Sonic is also arriving with Knuckles and Tails, who will join him in the game as Squaddies.

Squad Busters x Sonic update: New Squaddies and how to unlock them

You can unlock the new Hero, Sonic, along with the new Squaddies, Knuckles and Tails, arriving in the game.

Check out their powers first:

• Tails: Tails is a summoner Squaddie who uses his laser beam to blast through enemies. His Trait allows him to join your Squad, piloting his Cyclone Walker. However, the best part about having him in your team is that, after getting destroyed, he keeps fighting on foot until he respawns a few seconds later.
• Knuckle: Knuckle, on the other hand, can dig and dive underground to dodge enemy attacks successfully. He deals area damage when bursting out of the ground, making it harder for enemies to counter him. He can dig for loot, making him a great supplier. In his Super form, he will finish attacks with a visually pleasing spiraling upper-cut.

Both new Squaddies will have their Baby, Classic, and Super forms. Their powers and Traits will upgrade as you keep unlocking their new Evolutions.
