Campaign

In response to questions about the length of the single-player campaign, Infinity Ward CCO Jason West stated that Modern Warfare 2 would not be longer than the 6-10 hour-long campaign of Call of Duty 4. Mission settings in the game will include Russia, a military base in Kazakhstan, a desert area in Afghanistan, and Rio de Janeiro, Brazil. A trailer released on the official Infinity Ward Youtube page teased fighting at the United States Capitol in Washington, D.C., although it is unknown if the game will feature fighting in that setting . New features include the ability to dual wield handguns. 
Multiplayer
Special Ops

Modern Warfare 2 will feature a cooperative mode entitled Special Ops, which consists of independent missions similar in design to the "Mile High Club" epilogue mission from Call of Duty 4. These missions will take place in a variety of locations from the campaign mode, but are not related to story of the campaign itself. Special Ops supports cooperative play for up to two players, and can be played alone, in split-screen locally with another player, or online with another player. It includes such scenarios as a snowmobile race, a battle alongside U.S. Navy SEALs, and fending off a wave of 50 enemies at once. 

Special Ops is divided into separate groups of missions with changeable difficulty levels. The third group, "Charlie", includes the mission "Breach and Clear", where the objective is to just make it to the end of the level. At the beginning of a mission, players select what weapon to use from several scattered around a room before the actual mission commences. Once a choice has been made, a nearby wall is breached and the mission begins. At the end of each mission, a statistics screen displays how long the player took to complete the level and how many kills were scored. Successfully completing a mission earns the player stars, with missions completed on Veteran difficulty rewarding up to three stars. These stars can be used to unlock further missions in the mode.

Gameplay in the online multiplayer mode

The online multiplayer mode of Modern Warfare 2 retains the same experience points and unlockable reward system of Call of Duty 4: Modern Warfare, but also introduces several new features. Aside from new weapons and equipment, 15 different kill streak rewards can be unlocked and selected by the player. Among these is the ability to receive a supply drop after four kills, a predator missile strike after five kills, and to call in a strike by an AC-130 gunship after achieving 11 enemy kills in a row. It is also now possible to upgrade perks to a "pro version". Another new addition to online multiplayer, is in game host migration, which means that if the match host leaves the game, players will remain (instead of being reset to the game lobby like in Call of Duty 4) while a new host is selected and the game resumes.[20] Game modes include Free-For-All, Search & Destroy, Demolition, Domination, Team Deathmatch, and Capture The Flag. 

Assassin's Creed 2

Assassin's Creed II takes place in an open world and features nonlinear gameplay, allowing the player to free-roam the city at will. An article published in Game Informer reveals that Assassin's Creed II will grant the player the ability to swim and use the canals of Venice as hiding spots and will allow the player to drag city guards into the water as a means of assassination.[1] At E3 2009, it was also confirmed by the creative director that Ezio (the character that the player assumes control of during gameplay) will be able to "drive small boats." Historical figure Leonardo da Vinci is recreated within the game, as an aid to the player who provides a host of weapons and contraptions available for use.[1] At one point in the demo, the player can access Leonardo's flying machine which he actually built, keeping airborne using thermals from fires lit by friends gathered prior to the events in the demo.[1] The game will also feature a host of new mission types for the player to complete.

The health system has been adjusted to allow for a more dynamic and participatory experience, meaning that the "memory sync" system used in the first game only helps to recharge health up to a certain point. More grievous injuries will require a trip to one of the many street-side doctors, who can help return Ezio to full strength.

As well as using water as a hiding place, the player can utilize a broader array of scenery as cover and can now blend in with any crowd rather than a group of scholars dressed in white, as in Assassin's Creed. Like in the 2006 video game Hitman: Blood Money, there will be a notoriety system, and the player will become more notorious as Ezio completes more missions, however Ezio's infamy can be reduced by bribing, removing wanted posters of him or assassinating witnesses. Also, a day and night cycle has been added to the game, giving the sense of a passage of time but additionally certain missions will only be able to be performed during the day or night.[1] The game will also feature some sort of economic system that makes it possible to hire services from non-player characters, or "factions": Thieves, Prostitutes, and Mercenaries. Each faction has their own advantages. Thieves will help the player fight enemies and do certain activities like distracting guards, stealing money, and setting up fires for the use with the glider. Mercenaries will help in fighting and can also fight some people without involving the player himself in the fighting. Prostitutes act similarly to the monks in Assassin's Creed in that they can cover the player's presence from the guards. Additionally, they can distract guards. The player can find faction members inside cities or by going to the leader of a faction. Hiring them costs the player money, and if the faction members were recruited with help of a faction leader, the leader will require a favor from the player in order for the player to get any associated reward.

The trailer, which debuted at E3 2009, displayed many new things such as improved parkour mechanics. The main reveal of the trailer involved Ezio withdrawing his hidden blade to access a rudimentary gunpowder-based mechanic on his wristblade to take out a target from a distance. It has also been confirmed at E3 2009 that Desmond himself will "do more than just walk" in this game. Another feature, as seen in the gameplay video, no cover is safe, as guards can search them. To counter this Ezio has the ability to assassinate the incoming guards before detection, and placing the bodies in his former hiding location (he drags them into haystacks, places dead enemies on the bench he was sitting at between two allies etc.

Besides the main city of the game, the player can access hidden locations such as catacombs and caves, the contents of which have been compared by the developers to the Prince of Persia series. Exploring these locations rewards the player. It has also been said that the player can choose to throw money to the ground, which attracts the attention of nearby civilians, creating a distraction, and throw smokebombs in order to elude guards that are chasing him. Additionally, the eagle vision from the first game has been improved, now giving the option of remaining in third person with eagle vision initiated, allowing the player to spot targets while moving.
