Hello!
The big question - is Chaos better then Order? Is Chaos worth its money? It all depends on how you use it.
Now, before we begin, let me give a brief description of each chaos and Order unit.
Chaos:
Miner - Collects gold and mana, able to build turrets.
Crawler - A cheap, small, fast unit, but powerful in packs.
Dead - Range unit that throws its own poisonous guts.
Marrowkai - A skeleton mage that is able to attack lines of fists and send reapers.
Medusa - The queen of the Chaos, able to turn units in to stone and shoot poison onto the floor.
Bomber - Quickly trained, fast, and able to do massive damage in areas.
Juggerknight - A strong, armored knight able to charge and stun.
Eclipsor - A fast flying ranged unit, cheaper and trained more quickly then Albatross.
Giant - In one hand, holding a large club, and in another hand, holding a dead unit.
Order:
Miner - Collects gold and mana, able to build a protection wall.
Swordrath - Inexpensive sword unit, average health and attack, also able to rage.
Archidon - A ranged unit with low health, but able to outrun and out range some units.
Meric - A cleric who is able to heal units, cure from poison, and heal your monument.
Majikill - Leader of order, powerful mage able to electrify, poison, and fire.
Spearton - A unit with great health and armor, able to form a phalanx, and mostly used to take damage.
Shadowrath - A fast ninja, with the ability to become invisible, poison, and assassinate. Also, the enemy of Order giants.
Allbowtross - A slow, flying ranged unit, able to shoot flaming bolts.
Enslaved Giants - Captured Chaos giant, able to throw rocks, mostly used for defense.
Okay, now you know the units, so its time to see which unit would beat which.
Crawler vs Swordrath = Swordrath wins
Dead vs Archidon = Dead wins
Marrowkai vs Majikill = Majikill wins (with spells)
Medusa vs Meric = Medusa wins
Juggerknight vs Spearton = Juggerknight wins
Eclipsor vs Albowtross = Albowtross wins
Giant vs Enslaved Giant = Giant
Well, thats it.. for now.
