I have an extreme love-hate relationship with
Operation Flashpoint: Red River's artificial intelligence, though there's more hatred involved than love. The problems are placed under a magnifying glass in the form of a squad control interface called the QCR (Quick Command Radial). There are several permutations of orders to choose from, but of the commands featured, you'll be lucky to find four that actually work perfectly. Your squad has a mind (or should I say mindlessness) of its own, and they do a very poor job of following orders. Highlight an enemy emplacement and give the order "Flank Right," and play the Benny Hill theme as everybody charges straight forward. Some of the orders do work, but most don't.
On the good side of things, friendly bots are fantastic shots. You can probably make it through an entire mission without firing a single shot. Of course, you'll probably have to patch your buddies up a number of times, but it's still nice to see developers willing to put the emphasis on teamwork.
Speaking of teamwork, Operation Flashpoint: Red River was designed from the ground up to support four-player co-op. You can play the campaign with up to three other people, or you can dig into a handful of Fireteam Engagements. Naturally, if you have a buddy or three to replace the game's resident tactical dunces, the campaign experience improves. If you and your teammates have a good deal of patience and a keen eye for battlefield tactics, you might just find yourself having a good time putting insurgents in the ground and upgrading your loadouts as you progress through the game. However, you'll still have to deal with the dreadful pacing problems. The Fireteam Engagements are comprised of a few mission types, which range from defending positions and convoys to rescuing downed pilots to simply hunting all the bad guys down.
If you're in the market for a different kind of first-person shooter, Operation Flashpoint: Red River might have what you're looking for. You'll need to have an inclination for more thoughtful, slow-paced combat and a good bit of patience. If that describes what you're looking for, give Red River a shot. Just be prepared to deal with some issues here and there.
