Gameplay in Mass Effect 3 is influenced by decisions from Mass Effect and Mass Effect 2. Combat has been changed and refined; in particular, the cover system has been improved, there are more options for moving around the battlefield, instant melee kills and more conventional grenades are introduced as well as improved artificial intelligence. A four player multiplayer co-op mode will also be available.
Gameplay
Players with saved files from Mass Effect and Mass Effect 2 are given the option of importing them into Mass Effect 3.[16] If a saved file is imported, over 1,000 variables are pulled that will help shape how the final chapter is experienced.[17] If there are no saved files available, there are no origin-story comics for new players to help them make quick decisions like there were in Mass Effect 2.[18] Imported characters' appearance and class are changeable, with more features and hair-styles included in the character creator than in Mass Effect 2.[5][19] Commander Shepard will always start the game with some powers.[20] Upon finishing the game, there is a New Game+ option that allows players to continue playing after the main story ends or start again with their finished Shepard and collect items they missed the first time around.[21] The game has 82 minutes of cut-scenes.[22]Mass Effect 3 will have three pre-set campaign modes: Action Mode, Story Mode, and RPG Mode.[23] In Action Mode, conversations will have automatic replies and a normal combat difficulty. In Story Mode, conversations will have manual replies and a minimal combat difficulty. In RPG Mode, conversations will have manual replies and a normal combat difficulty. This last mode is reflective of the typical Mass Effect series experience. Overall, the RPG elements in the game have been improved over those in Mass Effect 2, with a more detailed leveling up system and increased weapon customization.[24] To level up characters, players will have skills that start along a single path and then eventually splinter into two branches where they can select only one upgrade or the other along a sequence of possibilities.[25] Players will also be able to customize their weapons with different scopes, mods, barrels and ammo types.[26] There are 25 weapon mods total — five per weapon type — and each of them will have multiple power levels to collect.[27] The game will include mini-games and Hammerhead and Mako missions.[5] To select dialog options, players can use Kinect to speak their choices instead of selecting them with a controller.[28]
As of August 23, 2011, BioWare has confirmed the return of previous characters Liara T'Soni, Kaidan Alenko or Ashley Williams, Miranda Lawson, the Illusive Man, Garrus Vakarian, Legion, Samara, Morinth, Tali'Zorah, Urdnot Wrex, Jack, Mordin Solus, David Anderson, Zaeed Massani, Kasumi Goto, Kelly Chambers, Thane Krios, Jacob Taylor and Ambassador Donnell Udina from Mass Effect and Mass Effect 2.[5][20][29] Some characters will not return if they were killed at any point during the previous games. The number of characters available as permanent squad mates are smaller than in Mass Effect 2 for the purposes of deeper relationships and more interesting interplay, including same-sex relationship options for both male and female Shepards.[30][31] If players achieved a love interest in both Mass Effect and Mass Effect 2, then both previous love interests vie for Shepard's attention in Mass Effect 3.[32] This "love triangle" is resolved by the end of the game. BioWare has also confirmed new characters names James Vega [33] (voiced by Freddy Prinze Jr.) and Diana Allers (voiced by Jessica Chobot).
The search and analysis mini-game has been changed from Mass Effect 2. Rather than scan individual planets, a setup described as tedious and boring[who?], the Normandy scans a region of space for salvage or War Assets. If these are detected on a planet, the scanner system is still used to locate, but planets are no longer scanned individually. If an area being scanned has been invaded by the Reapers, the Reapers will eventually detect the Normandy's scans and move to intercept it.
The ongoing war against the Reapers is controlled by War Assets and Military Readiness. War Assets are collected throughout the game or are provided from previous game accomplishments. Military Readiness is predominantly affected by the multiplayer aspects of the game. As the players Readiness increases, the War Assets become more valuable. The number of Assets and the players readiness determine the players success in the final war against the Reapers.
Combat
Combat in Mass Effect 3 has been changed and refined from Mass Effect 2, and further emphasis has been put on third-person perspective aspects to make the game more commercially viable.[34] In a preview for IGN, editor Arthur Gies went so far as to say the game "plays like a shooter" and that "combat-wise, Mass Effect 3 is in an entirely different space" from the first two games. In an article for bitgamer, Joe Martin gave a conflicting impression, noting that with regard to combat, "not a lot has changed".[35]The series' cover system has been improved so players no longer need to slide into cover and then hop over objects. Players will have more options for moving around the battlefield, including a refined sprint capability, combat rolling, and the use of climbable ladders. Players can also blindfire their weapons from covered positions, and have opportunities to shoot selected armor pieces and limbs off enemies.[21] Verbal orders can be issued to move squad mates and use their powers with the use of Kinect.[28] Moving and shooting, a "suicidal maneuver" in Mass Effect 2, will be a viable option because of a revised melee system.[36] Players are able to execute formidable punches and attacks, and instant melee kills are introduced specific to each class; for example, by holding down the melee button, a soldier Shepard will deliver a killing blow with a tech-blade in his/her wrist armor. Actual, round, conventional grenades will also be available.
Mass Effect 3 plans to be the most difficult in the series, with increased artificial intelligence to challenge players and increase the sense of reward.[37] Enemies no longer act as individuals as they did in the previous games, instead fighting and supporting each other in units. Enemies include 15-foot (4.6 m) tall Cerberus mechs, assault troopers, and ninja-style shock troops, as well as Reaperized husks of all races and Reaper ships ranging from 500 to 2,000 metres (1,600 to 6,600 ft) long.[38][39] Some changes are made to already-existing class types; for example, Engineers are able to build turrets.
Multiplayer
Mass Effect 3 will offer a multiplayer co-op mode called "Galaxy at War".[40] In the mode, players are able to play alongside up to three other players in unique missions that can impact the outcome of the single player campaign.[41] Each mission was designed specifically for multiplayer, and will involve taking over enemy strongholds. By completing these missions, players will give themselves a better chance of attaining a perfect ending in the single player campaign; although, they are not necessary to do so. The mode has been compared to Gears of War's horde mode.[42]No characters from the single player campaign are featured in the multiplayer mode. Players will create brand new characters for themselves and be able to play as members of non-human species, including asari, drell, krogans, salarians, and turians.[43] Every race will have unique powers – such as a "Krogan Charge" for krogans and different movement options out of cover between drell and humans.[44] All classes are playable.[42] The maximum level that created characters are able to reach is 20, and just like in the single player mode, leveling up will include skill branches.
The majority of missions are wave attacks in various locations against different enemy factions. The selections during configuring the game can affect experience gained and the overall difficulty of the mission. During the missions, random tasks will be assigned, allowing for the collection of credits to purchase equipment between missions. After a certain number of waves, the players retreat to an extraction point which they must hold until extracted.
Equipment and characters are acquired by the purchase of kits which contain random weapons, characters, and mods. The kits are purchased with multiplayer in-game credits or Microsoft Points.
Gameplay in the multiplayer mode will only allow for players to carry two guns at a time in their inventory, and there is no ring menu to change weapons; instead, weapons are changed by holding down a button.[44] Only three powers per class are also available as opposed to those available during the single player game.
