Depends, how long ago did you buy the game? What types of games are you playing and what level are you? You will notice a significant difference in play once you learn all the maps. Every level has a good amount of good hideouts and spots to shoot from. I usually play hardcore deathmatch, that way people dont just run out and shoot up everything. Its must less realistic when you can pump some guy with about 10 rounds and he is still standing. Hardcore, its usually the first guy to get the shots off is the guy standing at the end. 1,2, or 3 shots at most to kill someone. Here are my tips: Tip #1 - Use bouncing bettys. Plant them in high traffic areas, it will increase your kill count, and streaks which can rocket when you get to 5 ( artillery) and 7 (dogs). Dogs may be the best streak booster, even better then the helicopter in COD4. Tip #2 - Find a good hideout in each level. Actually, find two so your not predictable. Surround the entrances with betty's. Make sure your spot has a great vantage point to pick off enemies. Tip#3 - Get in a Tank! Enough said.... Tip #4 - Use Aperture, it significantly increases your aim. Tip #5 - STG-44. Best gun I have come across thus far. Tip #6 - Swap out your bouncing betty's as Perk #1 for Grenade launchers on levels that have tanks. Also make sure your primary grenade in these levels is the sticky grenade. Tip #7 - Stopping Power, it helps you kill your opponent before he kills you. Tip #8 - If your in the open and being shot at, jump sporadically. It will make them miss. I cant think of anymore now, I pretty tired. PM me if you want to know the good spots in each level. At least the ones that work for me.
