Castle Crashers is a four-player cartoony medieval weapons-based brawler available on PSN and Xbox Live. It was developed by members of Newgrounds.com, and it has the distinct visual style and dirty humor that site is known for. Its combat is very simple, although it features a unique magic system with a refilling mana bar. It also places a strong emphasis on RPG elements like gaining experience to level up stats, buying items, and finding new weapons. It has a whopping 31 characters.
Castle Crashers had a flash demo on Newgrounds where you fight Tom Fulp's beard.
The original build of Castle Crashers back in 2005 was on a Gamecube.
Castle Crashers has a cool style, lots of awesome moments, and a ton of hidden unlockables. It's the perfect brawler to play with groups of inexperienced friends. However, its super simple combat engine lacks a real sense of impact and is dissatisfying for hardcore players. There are a lot of enemies, but they're largely model-swaps of one another.
