In Call of Duty: Infinite Warfare, Frontline plays similar to Team Deathmatch with the exception being, everyone on one team always spawns on one side of a map or the base. At the base, the team that owns the base gets an armour bonus for for a limited time after they spawn while being at their base.
It is important to utilize teamwork and push engagements into the middle of the map, and if possible spawn trap the enemy by killing them in areas where they are exposed as soon as they leave their base's borders, as the enemy team can do the same should they get a successful rush.
