Brought to you by Epic Games and ChAIR entertainment, Infinity Blade was perhaps the most revolutionary game of 2010. Though it’s a pretty much just a touchscreen take on the hack-and-slash type game, it was the first game to use Epic’s new iOS port of the UNREAL engine. The graphics are simply stunning.

The graphics, in fact, are so stunning that you won’t be able to run the game on older devices. You will need an iPhone 4, iPhone 3Gs, third or fourth generation iPod Touch, or iPad in order to run it.

Infinity Blade is a hack-and-slash RPG where you roam a highly-detailed castle using a “tap to go there” movement system. You walk from one fight to the other, and collect the reward if you win. If you lose, you can heal up and restart the battle.

It can be a little repetitive if you sit down and play for a long session, but it’s good for a quick skirmish while you’re waiting somewhere.

Eventually you will level up and save enough money to purchase new equipment. It’s separated into different groups (swords, armor, magic rings, helmets, etc.) and can be managed from your Inventory screen once you have acquired an item.

Perhaps the most interesting, and most frustrating, part of the game is the endings. The story behind Infinity Blade is that you are part of a line of warriors sworn to fight the tyrannical god-king who rules over your fantasy realm. What happens is you quickly play through all of the fights leading up to the final boss battle, then he swiftly kills you. Then the title screen plays again, with an added message saying “18 years later.” You then play as your descendant, who looks strangely identical and has the same items…

Lather, rinse, repeat.

I assume you eventually level up to the point where you will stand a chance against the god-king, but I haven’t had the patience to yet.

The developers have promised a multiplayer function, as far back as the tech demo during the iPhone 4 keynote, but the update containing it has yet to come. Infinity Blade has made well over a million dollars in sales so far, so lack of popularity isn’t the reason. I suspect that once the update drops the game will become a lot more fun. I always enjoy doing local Bluetooth games when I have the chance. Hopefully it won’t be too much longer…

Infinity Blade is absolutely the most richly-detailed 3D game you will find on iOS to date, and is fun for casual gameplay. Whether it’s worth $5.99 is another matter. If you’re a fan of hack-and-slash games, you’ll like Infinity Blade. If you prefer adventurous questing and magic to swinging a sword around, you may be bored by the repetitive fighting action.
