The story (if you could call it that) is pretty simple. You and your Rainbow squad are out to stop a group of terrorists who have created a deadly virus. Between missions, you can select "Briefing" which will tell you exactly what is going on and why you are doing what you are doing. It doesn't automatically explain the "story" or reasons to you. Your mission objectives are always pretty much the same: save this hostage or disarm this bomb or disable this security device.

There are a handful of different mission modes. The Campaign missions take you through the "story mode" with a team and unlocks the next mission/map when you complete one. Lone Wolf mode does the same thing, except you do it with no other team members. Terrorist Hunt sets up a number of bad guys throughout the map, and your job is to go through and shoot them all. Lastly there is a Training mode for practice sake.

Before beginning each of the 16 missions, you'll want to outfit you and your team with whatever weapons tickle your fancy. This is my favorite part about the game. You can choose between 11 assault rifles, 9 submachine guns, 4 heavy machine guns, 5 shotguns, or a grenade launcher for your main weapon. You also get to choose one sidearm, decided from 6 different pistols or 2 shotguns. Most guns (but not all) can support optional attachments such as a scope or a suppressor. Below that, you can decide to take certain kinds of grenades such as frag, flash, smoke, or phosphorus. You can set each of these options for every one of your team mates, too.

The guns vary between their damage, firing rate, accuracy, and maneuverability. The assault rifles and submachine guns were pretty good, but the shotguns in this game are very lacking. In most FPS's, the shotgun is usually my favorite weapon, but not here. Even three feet away from an enemy I might find myself shooting four or more times trying to kill him. Unless you are in hugging range of the enemy (which is bad) the shotguns are almost worthless. I honestly ended up going through a whole mission using just my pistol because the bad guys laughed at my shotgun like it was a super soaker.

Speaking of the bad guys, this brings me to their rudimentary AI. Most of the time they are slow on the draw. I breezed through most missions by just running up and shooting them. Some enemies are tougher but only because of their positions. You can't exactly charge enemies on balconies or other high objects, but since you can usually see them before they react to you, taking them out from a distance is usually no problem. Equipping your gun with a scope really puts this on "easy mode" in that regard. However, there are ways you can make the game tougher. Don't use a scope and choose a weapon whose damage is low. If you select "Challenge" instead of "Normal" for the difficulty mode, it also removes the artificial crosshair from the screen, makes enemies tougher to kill, and makes you a little easier to kill. Doing this, I actually had more fun with the game.

Your team members are cursed with this poor AI, too. They're pretty good at blocking your shots by setting up a nice position in front of your gun. Luckily, there is no penalty for killing one of them. Many times I would try to back up out of a firefight only to run into a team member. They really like hunching up on you for some reason. Even if you give them the "hold" command, there are certain parts in the map where they automatically start to follow you again. Not a problem of course, since you can immediately tell them to wait again. My suggestion is to either shoot them off the bat with your sidearm, tell them to "hold position" on top of a live grenade, or just go with Lone Wolf mode. You really don't need these guys.

The graphics are pretty average; there is nothing that bad or that special about them. At least they took the time to put in different models for each gun. The various missions will take you into many different areas such as a desert village, a university, some catacombs, a hospital, and finally a pretty neat castle area. The maps were fairly well done, but felt lacking without many furnishings or things to destroy.

There is a multiplayer mode, but you'll have a tough time actually finding a worthwhile game to join. Not only are there very few players, but the small amount of games I was actually able to join were very laggy and it wasn't from my end. However, if you can get this going over a LAN or something with some friends, I can definitely see it being fun.

Despite the poor AI, I have to say that the game kept me interested enough to want to play it through to the end. There are indeed a few challenging spots, but many of the areas you can tap-dance through if you're at least average at first person shooters. I liked having enough guns where I could choose something different each mission. With the amount of all-around well done FPS's out there now, it would be hard for me to recommend picking this one up. However, if you can't get enough of FPS's and can find this in a bargain bin, it might provide you with 10+ hours of entertainment.
