Tips:
After you beat a campaine, you get to replay certain missions that you
 completed, but for some reason not all of them. When you beat other 
heroes camapines, some of their missions will be added to what you can 
replay. Once you beat all 7 campaines, you will have access to about 30 
missions, nomatter who you are. I recomend being walter or leinhart. 
Getting to level 99 isn\'t easy, you need around 550,000 experiance points. ruperts second to last mission isn\'t too hard, and you can get around 
25,000 experiance and lots of gold everytime. Once your main troop is 
good enough, you can solo most missions. Use a fire casting officer to
 kill swamp mammoths, and a ice casting officer to kill air (and use 
healing trees or enrage to heal). Also some missions will choose which 
units you use, like if you need sappers or fire arrows in order to complete 
a mission. You will not recieve experiance or gold from replaying final 
missions. And remember to get all your troops the best items available, 
some of wuich cost 30,000 gold. Enjoy. Yea, it gets boring real quick.
