ABOUT HELLDIVERS
The dystopian universe of Helldivers has mankind ruled by a 'managed democracy', an improvement of contemporary democracy where the outcome of elections are more predictable. The improved democracy has become more than a way of electing a government, it has become a creed by which the brainwashed inhabitants of Super Earth fight for - without fully acknowledging what it means.
Super Earth, the fictional futuristic Earth is beset on all sides by three hostile enemy races that, according to the government, in one way or another needs to be subdued. And while the Helldivers are a pure combat unit, they are often tasked with retrieving technology, activating oil-pumps or other activity that is deemed important by the government to preserve freedom and the 'way of life'.
GAMEPLAY
In Helldivers, the players need to learn to coordinate their actions during chaotic combat, to complete objectives and to avoid friendly-fire casualties. The game is set in a procedurally generated universe where the community must fight three different enemy species to ensure the survival of Super Earth. Gameplay takes place on procedurally-generated missions where players must accomplish a series of objectives. Unlike many similar games where fighting certain enemies in a certain order is mandatory, the players make their own decisions about where to drop, whether to go on foot or in vehicles, in what order objectives should be completed and when to call down certain pieces of equipment, referred to as stratagems within the game. Before missions, the players select from a wide variety of weapons and equipment; some strategems drop a cargo pod containing heavy weapons or vehicles to be operated by players, while others consist of orbital strikes, airdropped minefields or other support firepower.
To win, players must fight or sneak through enemy-controlled territory, complete objectives, and call a dropship to extract them from the planet. Outside of certain trophies/achievements, there are no rewards granted for simply killing enemies, which are endless. It is possible to hold out indefinitely against waves of defenders, calling in more and more ammunition and defenses and racking up huge kill counts, without making the slightest progress toward winning the mission.
Once on the planet's surface, play follows an escalating pattern. Weak enemy patrols crisscross the planet semi-randomly, keeping watch on objectives. Players can see nearby patrols on the radar, try to avoid them, or kill them before discovery. If they spot the player, they will quickly sound an alarm, calling in front-line troops to fight the players and interfere with completing objectives. Endless troops can pour in forever if the players continue to set off alerts. If the player can kill or escape from the responders without new alarms going off, the map will quiet down, giving players an opportunity to advance without resistance until the next alarm goes off. When all objectives are completed or failed, the players call the dropship. It takes 90 seconds to arrive, and during that time, hostiles are strongly attracted to the landing zone for a final fight. Entering the dropship completes the mission.
