If you're one of those people who just want to beat the game so you can fight with the demons, keep reading.
Naturally, the best race to choose for quick gaming is the undead. They have a massive halberd bonus with only their archery to lose, which for this strategy is unimportant.
At the beginning of the game, buy the halberd units. On the map, avoid the Orcs of the South and the Men of the West for a bit; they're hard because of their axe throwers and javelins. Of course, if you enter a battle with the OotS or the MotW and they DON'T have axe throwers or javelins, then by all means, fight them; they won't be as hard.
In normal battle, just hold down the space bar with the halberd units selected, which sends a line of halberdiers down the same lane. Naturally, the CPU will follow up by sending units down the same path. Your halberdiers will crush them. Don't worry about other units in other lanes; the gains will catch up with the losses. Keep an eye out for charges. When you can charge, charge with the halberdiers.
Once you have 1300 coin, buy the Flailer units. You can now essentially defeat the annoying OotS. What you do is wait for a flailer to become available, then send it out. Along the same line as the flailer, send maybe 5-7 spearmen, then repeat, always on the same line. Of course, the enemy will send axe throwers; however, the spearmen act as buffers for the failer, so the axemen are killing the spearmen, and the 2-hit-kill flailer remains safe. When you can charge, charge flailers. This is a slow but sure strategy. Just because the Orcs start winning doesn't mean the battle is over.
As you win (or lose) battles, use the money to buy Halberd upgrades. These MUST be the dominance of your purchases. I would only suggest buying one speed upgrade and one armour upgrade, then have the rest go into halberds.
Near the end of the game, you should only have the demons and the MotW left. Fight the Demons first. Using the first strategy really makes it easy.
Okay, now the only colours on the map screen should be White and Yellow. With all of the halberd upgrades, the battle should be easier; again, the first strategy should work to defeat these guys, but if at first you don't succeed, try again. Remember, for every battle you lose, you get free money. I highly advise against using the second strategy with the MotW. Their horsemen will plow right over you.
And that's the end. This should be effective in winning the game. Feel free to improve upon the strategy.
Oh, and I DO NOT know the cheat codes. Please don't ask.
lol Guys Men of The West are best for slow-but-sure players - My walkthrough would be to take the lowest percentage first - Fight ALL enemies (Exept Trolls) head on, you will win, make sure that u only use swordsmen, and you count 1 swordsmen for one of their enemies (Unless it's their special, use 3 for them), and you will either overpower, stay even and then use a charge, or, well there isn't a third, after two? No, no after two...
Keep doing this, do not attack the demons before all others are decimated, and wiped.... This is a plain strategy, but with a while it'll work nearly always
And btw, thanks for reading if you did...
If you're demon just use spearmen (and Master Spears) depending on the enemies, just get armor and spear upgrades, do not fight trolls head on though
yea i thought that this would be a bad walkthrough because i beat the game like when it first came out. i used this exact same stratagey but i didnt go all the upgrade points to the hallbreders. i upgraded speed a bunch to. good guide!
