The Spell Brigade
Small Belgian indie studio Bolt Blaster Games scored a hit with their survival/bullet hell game The Spell Brigade by mixing in online co-op elements - even with optional friendly fire that recalls the chaos of Magicka. It sold more than 125,000 copies in less than two months.
Following the huge success of Vampire Survivors, which impressed both critics and players despite its sparse presentation, and which recently surprised with a huge Castlevania DLC, many game developers tried their hand at a similar concept - a kind of reverse bullet-hell with rogue-lite upgrades, in which you have to survive as long as possible. Brotato by Blobfish from Switzerland and Halls of Torment by Chasing Carrots from Stuttgart were successful in this 'new genre' and brought some original ideas to the table, similar to the hugely successful Deep Rock Galactic Survivor, Soulstone Survivors or Death Must Die.
