Modern Warfare 2 - Tips Tricks and Tactics

Underpass is a very big map with many hiding spaces. A good way to find people on this map would be to use the sniper with thermal sights. To counter this you could use cold blooded though. There is not a general fighting area on this map. But there are may places that you sniper from. When sniping always remember to use claymores to keep doors protected, unless you are planning to try assualt sniping. At the start there will be many players with snipers over the bridge as this is where the two teams spawn. A big tip I would give on Underpass is to watch where you throw your care package/emergency airdrop as there is they can land on the overpass, i have done this many times and not been pleased with myself. When trying to use an assualt class I would try to not stay on the bridge too long as this is where a sniper will be looking, if you need to cross the bridge make it quick. Stealthy classes should try a longer route to get the enemies from behind. There are many ways to get to the other side of the map and many bushes to hide in on the way there. Below I will show a map of Underpass.
