Summitsphere’s chaotic platformer Antonblast just got “The End,” a massive free update with four new bosses, fresh challenge modes, and a big audiovisual overhaul. Here’s what’s inside and why you should finally pay attention.
Antonblast was already loud, messy, and gloriously destructive. Summitsphere built it as a playable tantrum, a side-scrolling platformer where you sprint through garish stages, smash everything with a gigantic hammer, then sprint back out before the level collapses. It wears its Wario Land inspiration proudly, from the chunky sprites and crunchy sound to the focus on mayhem over precision.
If you missed it at launch, the new free update, titled “The End,” is the perfect excuse to dive in. It does not just tack on a bonus stage or costume. It retools major systems, overhauls the entire soundtrack, and layers in new bosses and challenge modes that extend Antonblast well beyond a standard clear.
Four new Demon Corp bosses
“The End” centers on a set of brand new boss encounters that give more personality and teeth to the game’s demonic corporate villains. You now fight four individual members of Demon Corp, each presented as a distinct showpiece battle inside Brulo’s sprawling casino complex.
Each of these bosses guards a Prize Star and opens the door to their own big act. Structurally, they function as extra capstones to Antonblast’s wings, giving the casino hub a stronger sense of escalation. Where the original release already had loud, screen-filling encounters, these new fights push harder on pattern recognition and sustained pressure, testing how well you have internalized Antonblast’s aggressive movement and attack flow.
These Demon Corp bosses are not side curiosities. They fold directly into progression, feed into the game’s new challenge modes, and give veteran players something more technical to chew on after blitzing through the original adventure.
The Big Tournament: nine bosses, one shot
If those new fights are not enough, “The End” introduces The Big Tournament, a full-on boss rush that strings together nine major bosses. You tackle them back to back without being knocked out, chasing the title of Tournament Champion and a hefty in-game cash payout.
Antonblast is built around high-commitment offense. You want to be up in enemies’ faces, swinging the Mighty F’n Hammer and chaining movement into attacks. In regular stages, that reckless approach is part of the fun. In The Big Tournament, it becomes a genuine risk. Misreads and greedy hits add up quickly when health does not refresh between bouts.
The result is a mode that reframes fights you already know. Patterns that felt loose and chaotic in the campaign become tight tests of resource management and consistency. The rush format also plays into Antonblast’s speedrunning potential, rewarding players who study openings and learn how to end phases before the screen fills with hazards.
Lime Trials: time‑attack gauntlets with a twist
Another new pillar of “The End” is Lime Trials, a set of timed challenges tied to the bosses of each casino wing. Once you have beaten a wing’s boss, you unlock its corresponding trial.
Instead of simply racing to a finish line, Lime Trials ask you to collect all the Limes scattered through a stage before the clock hits zero. Clearing a trial earns you Souvenir Limes, while replaying lets you chase faster times and extra cash.
Lime Trials lean into Antonblast’s level design strengths. Stages are already built around breakable walls, hidden alcoves, and routes that only become obvious once you have torn the scenery apart. With a timer hanging over your head, every shortcut and background detail matters. It pushes you to approach familiar levels like puzzles, shaving off seconds by remembering where to crash through a wall or bounce off an enemy instead of taking the long way around.
For players who already sprinted through the main adventure, Lime Trials create a second layer of mastery. You are no longer just escaping an exploding level, you are routing it.
New modes for replay addicts
Beyond individual challenges, “The End” bolsters Antonblast’s replay value with fresh global modes that remix the whole campaign.
The centerpiece for difficulty tweakers is Hard Mode. Once you clear the first stage, you can flip to this tougher variant, which cranks up enemy resistance and boss intensity while dialing back assists. It respects your time by enabling it early, so if the default balance feels too forgiving, you can effectively play the entire game under stricter rules.
Then there is Stage Rush Mode, unlocked after defeating the Final Boss. This is essentially a speedrun-friendly circuit through all 12 stages and 8 bosses of the Adventure campaign. It tracks your performance as a continuous run, encouraging you to refine not just individual level strats but transitions, menuing, and boss execution.
Together with The Big Tournament and Lime Trials, these modes turn Antonblast into a platformer you can keep returning to, rather than one you shelve after a single weekend.
Danton, trinkets, and hidden spray cans
“The End” is not only about high pressure content. It also deepens Antonblast’s hub and collection systems, giving players more reasons to poke into corners between big set pieces.
A new roaming Danton NPC now wanders Brulo’s Casino. Talking to him helps the space feel more like a living, eccentric venue instead of a static menu hub, and he acts as a character anchor for some of the new content.
In Brulo’s Shop, the update adds fresh trinkets such as things like the Virtual Visor, Game Brick, and Pet Paint. These are not just shallow cosmetics. They tweak how Anton and Annie’s adventure looks or feels, layering playful filters and small mechanical wrinkles onto runs. It fits the game’s throwback energy, like you are slotting strange cartridges into an already odd console.
Collectible fans get even more to chase. “The End” scatters 16 new Spray Cans across Brulo’s Casino and Peanut Park, bumping the total to 110. They are tucked into nooks, branches, and secret paths, designed to tempt players who like to double back through levels hunting for the last few missing items.
A small set of four new achievements ties into these additions, particularly secrets in Peanut Park and the new stages and bosses. It rounds out the update with clear checklists for completionists who want proof they have seen everything.
A calmer, cleaner Antonblast
Antonblast’s sense of style has always been loud. Backgrounds pulse with color, sprites smack into each other with improbable force, and the soundtrack blasts away on crunchy percussion and big hooks. For some players, that intensity bordered on overwhelming.
“The End” tackles that with a major audio overhaul. The developers have gone back and replaced the entire soundtrack with an updated version, while also rebalancing sound effects and levels. The goal is to preserve the game’s unruly energy but strip out clipping, harsh peaks, and the kind of wall-of-noise mix that could get exhausting over long sessions.
It is an unusual move to see a studio effectively relaunch their soundtrack this late, but it lines up with Summitsphere’s attitude toward Antonblast as a living project rather than a fixed release. If you bounced off the original mix, this is a good time to give it another shot.
Beyond audio, the update packs in bug fixes, polish passes, and tweaks across the board. Animations and feedback are sharper, difficulty spikes are tuned, and little rough edges from launch have been sanded down. The team also hints at additional secrets that only become obvious if you chase the new modes to their conclusion.
Broader support and a second debut
“The End” also expands Antonblast’s language options, adding support for English, French, German, Spanish, Italian, Portuguese, Latin American Spanish, and Brazilian Portuguese. That broader localization makes it easier for more players to experience the game in their native languages.
Taken together, all of this makes “The End” feel less like a final patch and more like a soft relaunch. If you watched Antonblast’s pre-release buzz, compared it to Wario’s Game Boy classics, and then forgot to pick it up, this is your cue.
At its core, Antonblast is still the same bruiser of a platformer, built on the thrill of smashing stages apart and racing the fallout. With new bosses, challenging modes, collectible hunts, and a cleaned-up audiovisual presentation, it finally has the long tail and polish to match its first impression. In other words, this might actually be the best moment to start Anton’s rampage.
