Warlords: Call to Arms is a very popular flash game on the Internet. Unlike most flash games, it has a long beat time and is very challenging. The first few times I played I kept losing constantly. After a while I felt that anyone could win. I have to avoid the troubles I had to deal with.
The first thing you want to do is choose a race that warlord games has a good starting melee weapon stats. I recommend the undead or men of the west. The undead offer +3 stats to halberd and men of the west offer +2 stats to swords.
The reason you must choose a race with optimal melee stats is because they key to beating this game is fighting the strongest race first. I know it sounds counter intuitive but it works. Having higher stat melee weapons makes the process easier.
After the race you have chosen, the next thing you want to do is to challenge the race of demons because they are the strongest. If you don't beat them first then they will be very strong later and you will win.
They are important for beating monsters, sending troops in a straight line with the highest melee weapon stat. You will literally send 100 soldiers in a straight line. It will eventually dominate the monsters and you will win.
