The kingdom calls it a happy ending: the day the evil wizard was sealed away. A thousand years later, the wizard has woken up and has other ideas. Bunch of Idiots Studio, the one-person indie outfit run by Romanian developer Sergiu Pert, will release its action tower defense game Evilos on Steam on December 14.
Alongside the release date, the studio debuted a new trailer showing off the game’s distinctive mechanics.
Evilos breaks from the typical tower defense formula of protecting a castle or kingdom from waves of monsters. Instead, players become the powerful final boss trying to bring the kingdom down, a role-reversal concept front and center in the game’s design.
Players devise their own strategies and unleash action to break through heroes and the kingdom’s defenses, promising a destructive, playful kind of fun the genre rarely offers.
An Evil Wizard’s Revenge, a Thousand Years in the Making
Players take on the role of an ancient evil wizard who awakens from a thousand-year slumber to reclaim the power stolen when he was sealed away.
The kingdom has long celebrated the wizard’s sealing as its peaceful “happy ending.” Now awake, the wizard fends off the waves of heroes and champions sent to defeat him, and launches a ruthless campaign of revenge to topple the kingdom in turn.
According to the developer, Evilos draws heavy inspiration from Swamp Attack, the hit mobile tower defense game.
But where Swamp Attack follows the traditional approach of holding off incoming monsters, Evilos turns it around: the player is the final boss, facing down the righteous heroes who come to hunt him.
Spells, Magic Guns, and an Undead Entourage
The wizard’s dark magic hits hard. In battle, players can cast screen-filling area spells such as meteors, tornadoes, and lightning. A magic gun system adds satisfying feedback, with each weapon carrying its own elemental effect: freezing, burning, electrocuting, or disintegrating enemies.
Weapons and spells can be continually upgraded and evolved into more powerful forms, and combining abilities creates explosive synergies in battle.
True to an ancient wizard, a necromancy system lets players raise the dead as minions. Their names stand out: Jack Marrow, Nicolas Ribcage, Scary Potter, Vincent Van Gore, and Arnold Schwarzenecro. The playful riffs on famous names from pop culture set the tone for the game’s cheeky black comedy.
100 Levels Across the Kingdom, Each Act Capped by a Boss
Evilos offers 10 acts and 100 levels spread across the entire kingdom. Players conquer the realm one region at a time, and every act ends with a powerful boss battle.
The game is single-player only, and the Steam store page classifies it as action strategy, blending tower defense, strategy, and hard-hitting action.
A One-Person Romanian Studio
Evilos is developed and published by Bunch of Idiots Studio, a one-person studio run by Romanian developer Sergiu Pert.
A free demo is available on Steam ahead of launch, and Evilos is also taking part in Steam Next Fest from October 19 to 26. The game supports Korean interface and subtitles.
Who This Is For
Strong fit for: tower defense fans looking for a fresh twist; players who enjoy playing the villain; fans of Swamp Attack and other action-heavy defense games; anyone who loves screen-filling spells, upgrade trees, and build synergies; players who appreciate goofy black comedy.
Cautious fit for: players expecting deep, slow-paced tower placement strategy; the emphasis is on direct action.
Less ideal for: those looking for multiplayer, as the game is single-player only.
What to Watch For
Next Fest demo feedback will show how well the role reversal holds up over a long campaign, and whether 100 levels stay varied enough. Pricing and the full language list should be confirmed closer to the December 14 launch.
The Takeaway
Evilos takes a simple but delightful twist and runs with it: for once, you’re not the hero defending the kingdom, you’re the ancient evil it thought it had defeated. Meteors, elemental magic guns, an undead crew with groan-worthy pun names, and 100 levels capped by boss fights make it a confident solo project with a clear sense of humor. Try the demo during Next Fest, then mark December 14 for the wizard’s return.
Free demo: available now on Steam. Full release: December 14, 2026.
