<P> While the previous games in the Killzone series portrayed a large war - zone with numerous allies by the players side at any given time and an overall linear design, Killzone Shadow Fall opts for a more open - ended level design and allows players to utilize stealth to approach their missions in addition to engaging in direct confrontations with enemies . Levels are much more open than in previous games, allowing for multiple ways / routes to complete objectives . Also in Shadow Fall, for the first half of the campaign, the player is alone in firefights, with the OWL as the player's only "companion", which is able to lay down cover fire, among other abilities . During the second half onward, the player is occasionally joined by Echo as an ally, where she is able to snipe enemies marked by the player . </P> <P> Multiplayer shipped with 10 maps . Users are encouraged to create their own custom map presets called "Warzones", which then can be shared with others or promoted by the Killzone community . Classes, abilities and weapons are unlocked from the start . The class system has been simplified to just three: Assault, Scout and Support (with some medic abilities from previous games now subsumed under "Support"). The player unlocks skill enhancements based on completing challenges unique to his class . Alongside competitive multiplayer, a 4 - player online co-operative mode was introduced with the Intercept expansion pack, released on 24 June 2014 . </P> <P> Following the Petrusite detonation that rendered the planet Helghan uninhabitable in Killzone 3 (an event now referred to as "The Terracide"), the ISA grants refuge to the Helghast survivors on the planet Vekta, allowing them to colonize half the planet, with that half of the planet dubbed New Helghan . A massive security fortification called The Wall is constructed to separate the two civilizations from each other, due to the resentment they bear over the previous war . Both the Vektans and Helghast routinely perform covert operations against each other in the hope of finishing the war each claims the other started . The majority of the game takes place in Vekta City, home to the Vektan Security Agency (VSA) headquarters, as well as a prison in New Helghan, and Helghan, the original homeworld of the Helghast, now dead and shattered due to the Petrusite detonation . </P> <P> The game begins in the year 2370, several years after the construction of "The Wall", during the forced relocation of Vektans out of New Helghan . Michael Kellan and his 5 - year - old son, Lucas, attempt to sneak through New Helghan to The Wall . Along the way, they meet Sinclair, a Shadow Marshal, who aids them in making it through to safety . Just as the group makes it to The Wall, Helghast forces spot them and kill Michael . After Sinclair dispatches the remaining forces, he promises Lucas that he will look after him . A brief cutscene plays, showing Lucas rising through the ranks of the Shadow Marshal Academy, eventually becoming a full - fledged Shadow Marshal and working under Sinclair's command . </P>
