COD 5 has received loads of praise and incredibly high sales since its release, so you can just about guarantee that you'll have immense fun playing this action game. COD Worlds at War is a first person shooter game with elements of historic action, as the game is set in WWII.

You will find that Call of Duty 5 is a great game that doesn't miss a beat from the time you open the game's package until you complete all the achievements and finish the game in its entirety. There are just loads of multi-layer componetes as well as solo mode features that any action gamer will appreciate.

Although, you will find that the overall interface could be better, as there isn't a lot of emphasis on the stylistic end of the game, the cinematics are pretty impressive. The graphics and the overall color scheme show a lot of greens and browns, as you are in war, but the overall details and effects are great.

Again, the cinematics are great, meaning the sound quality and sound effects are big.

The gameplay is pretty strong, but at times the mini-games can hold back the overall gameplay of the main storyline. But, with 26 different missions, loads of achievements that you can earn, stat tracking, online multi-player mode, and a challenge mode, you'll find that Call of Duty: Worlds at War offers room for more entertainment.

• Crouching and proning are important tips for survival. You will reduce your chances of further damage when you are under heavy fire. Plus, when you prone, you can get more advanced and reload.
• When you are under firre, remember to find cover because your health will refill with the quick rest. But, never assume that your cover is save, which is where crouching and proning help out.
• Although you are less likely to get a direct shot to the head, when you aim without using your sights, sometimes you will find that you can hit the enemy much quicker.
• Press the 'Aim' button when enemies are in front of you, and you will be able to auto-aim on that enemy. Again, it's not likely that you'll get an automatic shot to the head, but it'll definitely make your aim quicker.
• "Cook" your grenades by holding down the grenade button and letting go. This will reduce the time that your enemy has to throw the grenade back at you. Just make sure not to hold it down too long.
• Sometimes you can toss a live grenade back, but make sure that when you see the grenade indicator you run away or quickly go to the source and attempt to toss it back.
• If you see the grenade indicator, press the 'run' button and go as far away as you can. If you see the grenade coming in, then you can try to toss it back, but if it's already sitting there, just run.
• When in the Japanese portion of the game, make sure that you don't forget about the 'melee' button. Press it when there is an enemey near, and they'll die. You'll also want to press the button if you're caught by a banzai, but you'll need to wait until the perfect time or you'll miss the timing.
• If you get lost, you can follow your friends.
• When in battle, if you can see a name over a person that you're aiming at, you don't want to shoot because that person is an ally.
• When you're fighting an almost infinite stream of enemies, you'll find that advancing their position is the only way to stop the flow.
• Keep your eyes out for side areas and guns leaning against walls, as those are weapons that are typically worth finding. You can carry two guns at once, so make sure to keep the best ones that you find and discard the others.
