The story involves Seig Warheit, a swordsman who faces off against his old friend Victor Delacroix, a rival swordsman who has fallen to the dark side and needs to be stopped. Seig rises to the occasion to battle a swarm of demons with the help of legions, demons with specific abilities that fight by your side.

To do battle players can attack, lock-on, and summon a legion. A legion can be accessed with one hit of the L trigger button and can be set to automatically bash enemies, or be set to a passive mode and attack when needed. Seig can lock-on to an enemy using an energy punch. The lock-on punch doubles as a combo linker and sets the legion to attack a particular enemy. Seig can use a legion up until his soul power runs out. To get more simply whack enemies and they'll fly right towards you, Onimusha style.

There's a simple premise to Chaos Legion – kill everything. Levels are comprised of sectors containing masses of mutant enemies. Dispose of them and it's on to the next round. At the end of each level is a giant end boss. Beat it and you gain another legion addition to add to your arsenal.

Unfortunately every level is more or less the same. Seig can constantly bash his swarm of enemies with one button, while the legion pummels on its own. After a level is completed, it's just another similar barrage of enemies.

Speaking of repetition, the backdrops in each level are painfully similar. Besides a lot of fighting areas being square shaped, each levels' textures and colors look much the same and hardly act as a intrinsic part of the action. The camera can be frustrating when it zooms in on the main character, preventing view of the surrounding enemies. It can be adjusted however with the right analog.

What Chaos Legion does well is its intense amount action. A ton of enemies litter the screen at once and is an impressive feat to see. The character and monster designs are terrific, as are texture grade and detail. There are some decent special effects with each enemy smack, and whenever Seig summons a legion, it's fun to watch the surrounding enemies fall flat on their asses.

There a few strategy elements in CL. Players will be able to select their preferred legion, upgrade energy bars, increase soul power, and other elements. But in an action game where little more than the same is performed over and over, the customization doesn't seem necessary. The soundtrack is standard up beat rock fare to accompany the fast action. There's nothing particularly special, but the enemy hits to make a decent impact. The voice acting in cinemas is pretty horrendous. About a notch better than the original Resident Evil.

Chaos Legion is like a full-priced Serious Sam title. It's fine if you want to jump right into an action-packed mashing session. Just don't expect it to keep your interest past 30 minutes.
