Initially released in 2008 on Xbox Arcade for the 360, Castle Crashers is a bonafide classic beat-em-up released on Steam in 2012. It has a charming art style and frantic 2D brawling solo or with up to four friends online or locally.
The game is celebrating the news of the upcoming Painter Boss Paradise DLC with a massive 90% discount that lasts until February 17. Your goal is simple - Pound away at an assortment of varied baddies and save the princess.
What makes Castle Crashers stand out is the variety in terms of characters and weapons. You have over 25 characters to unlock and more than 40 weapons to pick from. On top of that, some light RPG mechanics let you adjust your character's strength, magic, defense, and agility.
You also have animal orbs that grant you different abilities to aid your heroic onslaught. After you finish the main quest, you can engage in the PvP arena for one-on-one or team skirmishes. Then there is the insane mode that tweaks the campaign difficulty to be extra challenging, and mini-games like Back Off Barbarian, where you must jump and hop to avoid enemies.
There is also a free demo to try out. You can grab the game at a discount here.
