Call of Duty: Modern Warfare 3 has the following styles of gameplay.
- In a first person style game the main viewpoint is from the player looking forward. This can be either a first person shooter or a first person driving game.
- Action games are fast paced and tend to put the player in the middle of the action, requiring you to jump over obstacles, climb ladders, and shoot things.
- Shooter games are fast paced action games that are based on testing the players reaction time. They usually involve the player holding a weapon in front of them and attempting to shoot other players or characters. Some shooters are short lived arcade style, but most have both a single player mission series and some have a large multiplayer following. Common shooters include Call of Duty and Battlefield.
Port Forward Call of Duty: Modern Warfare 3
When you are playing Call of Duty: Modern Warfare 3 you might need to forward some ports in your router. Forwarding ports is a useful trick in gaming because it can really help to make your network connection most stable and intermittently even faster. Routers were not designed to allow incoming network requests and some games can play tremendously better if an incoming connection is forwarded through the router to the game.
Before You Forward a Port
Before you can forward a port you need to know the following things:
- Your router's IP address.
- The IP address of the device that the game will play on: either your computer or your console.
- A list of TCP and UDP ports that need to be forwarded.
How to find your router's IP Address
The easiest way to locate your router's IP address is to run our free Router Detector utility. It's a part of the Network Utilities suite of tools and it's completely free to use.
How To Forward Ports
A smart way to forward your ports is to use Network Utilities. Since Network Utilities allows you to both forward and un-forward ports easily you can keep your network security maximized, and then forward ports only when you need them. Alternatively you can do it by hand.
The usual process for forwarding a port is:
- Login to your router.
- Find your routers port forwarding section.
- Put the IP address of your computer or gaming console in the appropriate box in your router.
- Put the TCP and UDP ports for your game in the matching boxes in your router.
- Intermittently you have to reboot your router for the changes to take effect.
