NEED FOR SPEED WORLD

 Need for Speed: World (previously known as Need for Speed: World Online) is the 15th installment in the long-running racing video game Need for Speed franchise published by Electronic Arts. This iteration has been co-developed by EA Black Box and EA Singapore. It is the first MMORG in theNeed for Speed series (though Motor City Online was originally conceived as a Need for Speed game) and is available exclusively for Windows-basedPCs. World was released worldwide on July 27, 2010. However, people who ordered the Need for Speed: World Starter Pack had an early "head-start" in the game, which started on July 20, 2010.

 World takes on the gameplay style of Most Wanted and Carbon, focusing on illegal racing, tuning and police chases, and adds classic MMO elements to the mix such as special abilities. World also features the cities of Rockport and Palmont, the cities of Most Wanted and Carbon into its map design. The game currently features 34 different cars. In December 2010, the car Performance Customization was made available to players. On March 16, 2011, the Visual Customization was also made available. On March 31, 2011, the game introduced a new game mode called "Team Escape", a co-op version of pursuits which up to four players must race as a team driving from point A to point B while avoiding numerous cops. For this mode, two co-op versions of the game's powerups have been released.

Before September 8, 2010, after reaching level 10 and access to only tier 1 and certain tier 2 cars, the player would not be able to progress further in the game and would cease to earn any more experience points or cash. To continue the game, the player had to purchase the Need for Speed World Starter Pack. Without it, the player was allowed to play the game for as long as he or she wants, but he or she would cease to earn experience and cash. On September 8, 2010 World had passed 1 million registrations. To celebrate that, the game was made free-to-play and the level cap was removed.

The game was first announced to be free-to-play. In October 2009, World was opened to public beta-testing limited to residents of Taiwan. There have been seven closed beta sessions in total. Except the first one, all were available worldwide to residents who sign up, meet admission criteria, and get accepted.

NEED FOR SPEED HOT PURSUIT

 Hot Pursuit goes back to the Need for Speed series' roots and takes on the gameplay style of earlier "Hot Pursuit" titles in the Need for Speed franchise with exotic cars and high-speed police chases. It is primarily inspired by the original Need for Speed on 3DO.^{[citation needed]} Hot Pursuit lets players be either a cop or a racer and features a full career mode for both roles. The relationship between the cops and racers is described as "a dog chasing down a rabbit", with the cops being more powerful compared to the racers. Each side has several power-ups including calling for roadblocks and radar jamming.^[12] According to Criterion the single-player section is somewhere between 12–15 hours long, but with lots of replay value.^[13]

The game takes place in fictional location known as Seacrest County. It's an open world and features over 100 miles (160 km) of open road, four times larger than that of Burnout Paradise, Criterion's previous title.

Hot Pursuit features a new social interaction system called "Autolog" described as "Facebook for the game". The game features both single-player and multiplayer game modes with up to eight players; as an option to live multiplayer racing, players can post records and achievements on the Autolog feed for friends to see, which they then can try to beat. Autolog also contains an experience system called "Bounty".

The driving model of the game is described as "fun and accessible", not as arcade-styled as Burnout Paradise, but far from a simulator. All vehicles in Hot Pursuit are licensed real-world cars and SUVs, described as "all the cars you dreamed of driving, in the way you dreamed of driving them". Most vehicles are available in both racer and police variants, but a few are exclusive to each side. Also exclusively featured in the Hot Pursuit is the Porsche 918 Spider. Ferrari however, last seen in a Shift DLC-pack but notably absent from all other Need for Speed games since Hot Pursuit 2, is also absent from Hot Pursuit.

MULTI PLAYER
Call of Duty 4 features team-based and deathmatch-based multiplayer modes on various maps. Each modehas an objective that requires unique strategies to complete.^[5] Players can call in UAV reconnaissancescans, air strikes, and attack helicopters, when they achieve three-, five-, and seven-enemy kill streaks respectively.^[4] A game ends when either a team or player has reached a predefined number of points, or the allotted time expires in which case the team or player with the most points wins. If the points are even when the time expires, Sudden Death mode is activated in which there is no re-spawning and the team who either has the last man standing, or achieves the objective first are the winners. If the player is in either of the two matches, then there is an Overtime match, in which the next team to win is rewarded the victory.^[5]
The player's performance in the multiplayer mode is tracked with experience points, which can be earned by killing opposing players, completing challenges, completing objectives, or by completing a round or match. As the player gains experience, they advance in level, unlocking new weapons, perks, challenges, and gameplay modes. The highest obtainable level is 55, but on the console versions of the game, the player has the option to enter "Prestige" mode, which returns their level to one and removes all accumulated unlockables. This process can be repeated up to 10 times with a different insignia being given each time.^[6]
