Most first-person shooters have a simple way to keep track of kills: the harder it is to kill someone, the more points you get. This means that if you kill someone with a knife, you will get more points than if you killed them with a chain gun. However, unless you are very good at the game, running around with just your knife is a risky move. Most of the time, this way of playing will make you the worst player.
One way to get a good score is to use a long-range weapon like a sniper rifle and camp out near where the enemy camps spawn. If you do this, every time someone on the other team dies, they will immediately go back to the spawn point, where you can shoot them. They will then disappear and come back, where you can shoot them again.
This way, you get fewer points, but it's the same as when you play roulette in a casino: it's easier to get a lot of small wins than one big one.
When you use this method, try to pick your sniping spot with your head instead of just taking a chance. You will want to be up high, but if you can get a good shot from a lower spot, that might be the last place someone looks for you. Many newer first-person games let you use the sun like you would in real life. So, going up a hill and having the sun at your back will give you a natural advantage in the game and let you snipe from the same spot for longer before someone finds you and kills you.
Working together with other players is another way to get a higher score. Most people who play First-Person Shooters do so alone, with the goal of killing everything that moves. However, if you play with friends, you can use each other like you would in real combat. Now that you have other people watching your back as a unit, you can be a better killer in the game. For example, in some Delta Force games, you can take a helicopter and if your friend is flying it, you and another friend can man the chain guns and cover a bigger area. If you make a plan before you start the game, you can develop a good strategy like a professional gambler or Online Poker player would let you focus on one part of the game instead of many different parts.
Many times, I would jump into the pilot's seat with other players and circle the enemy camp, but the players in the back of my helicopter would not attack. Instead, they would jump out or wait for me to land instead of helping me attack from the air. So instead of working together to improve our chances of winning, they just wanted to be a team of 1. This will make it harder for our team to win the game, just like a player at a blackjack table can make all the other players lose by making bad decisions when it is that player's turn.
If you come up with a good strategy, play as a team, and use all the tools at your disposal, you can not only win more games and get more points, but you will also enjoy online gaming more. This is true for both first-person shooter games and online casinos.
