Castle Crashers/Barbarian War
Introduction
Barbarian War is the third level in Castle Crashers. For new players, it's quite hard to handle. However, once you know how things work, it's easy. The main enemies are Barbarians and the boss of this level is the Ram-Mobile.
Guide
Note: This guide is on Insane Mode. If you're still playing in Normal Mode, keep reading! It's better to know a little bit more :)
Let's begin!
First Wave: 5 Barbarians 
Leaving the castle, you'll find two Grey Knights 
fighting some Barbarians. Help your allies by trying to group your enemies then use your splash attack to damage them at the same time. If you know how to "air-juggling" your enemies, try that - It's an effective attacking method on Insane Mode. Some other combos work well too. Visit the Combos page and Enemies for more details.
Second Wave: 6 Barbarians
Moving to the right, you'll see a Barbarian punching a Grey Knight. Knock that Barbarian off the Grey Knight and he will fight with you. Then, more Barbarians will come, trying to overwhelm you. But don't worry, keep spamming magic and air-juggling and you'll be fine. Remember to collect food from fallen enemies in order to heal yourself.
Third Wave: 6 Barbarians
This wave is pretty similar to the Second Wave. However, this fight takes place near a destroyed catapult. You can use the broken parts of the catapult as obstacles to block the arrows from the Barbarians.
Fourth Wave: 6 Barbarians , 2 Theives 
Keep moving to the right, you'll see 2 Theives raiding some dead bodies. Take out the closet Thief and leave the other one. Now, a group of Barbarians will ambush you. Remember, keep spamming magic and air-juggling and you'll be OK. If the other Theif join in the fight, this could be a problem as he shoots his arrows in a straight line. However, if you know when he's about to shoot, raise your shield to block it. Note: The Theif will drop the bow when defeated if you don't yet have the bow which can be picked up.
Fifth Wave: 5 Barbarians
Moving forward, you'll see a big puddle of water. However, water slows you down, so don't walk there no matter what. Later, a Barbarian will run to you while carrying a flag. Wait until he leaves the puddle of water and drops the flag then attack him. (While carrying the flag, that Barbarian is immune to damage and water slowdown). Other Barbarians will show up and aid him. Defeat them should be easy.
Sixth Wave: Ram-Mobile
If you're low on health, cut the grass to find food to heal yourself before fighting the boss. First, the Ram-Mobile will come to you at a great speed (It'll try to ram you, so dodge) and shoot canonballs at you (The red X on the ground indicates where each canonball will land, so avoid it). It'll repeat this process twice before slowing down and unloading Barbarians to fight you. <to be continued>
