Doom's single-player mode has "badass demons, big effing guns, and moving really fast" as key principles, according to id Software Executive Producer Marty Stratton.[2] Throughout levels of industrial and corporate fields of a Union Aerospace Corporation (UAC) research facility on Mars and then of Hell,[3] as the combat system puts emphasis upon momentum and speed, the game allows players to perform movements such as double-jumps and ledge-climbs. The approach is known as "push-forward combat", which discourages players, playing from the "Doom Slayer"'s perspective, from taking cover behind obstacles or resting to regain health. Players instead collect health and armour pick-ups scattered throughout levels or kill enemies to regain health. "Glory Kills" is a newly introduced melee execution system wherein, when enough damage has been dealt to an enemy, the game will highlight it[4] and allow the player to perform a quick and violent melee takedown.
