Vigor is an online free-to-play survival shooter game set in post-apocalyptic Norway. The goal is to stay alive and upgrade an abandoned shelter that will protect the player against the harsh environment.

Players called Outlanders must seek resources and better equipment during Encounters with other players, although fighting them is not required. Only care packages or self defense enforce the use of violence. Every Encounter has a map that shows all exit points to players, as well as Points of Interest (POIs), such as hideouts, outposts, houses, a radio tower, and a transformer station. The POIs can offer valuable resources to help players upgrade their Shelter and reach its maximum level. Doing so will generate more materials and food to use, as well as reduce the crafting time for weapons and consumables. There are also places called Loot Events such as the Barred House, the Locked Container and the Timed Safe. These Loot Events offer significantly better loot than POIs and their content can be upgraded by Crowns in the game lobby before the Encounter starts.

An important aspect of an Encounter is the airdrop. These are crates containing valuable loot such as weapon and consumable blueprints, resources, weapon skins, and Crowns (in-game currency). These are dropped by a C-130 or AC-130, and signal that radiation will start appearing soon. The rarity of the airdrop can be upgraded in the game lobby using Crowns. The map shows the general location where the airdrop will happen, but there are options to change the location by using the Comm Station. Airdrops are not triggered by players and instead occur at a predetermined time. When a player picks up an airdrop, their location is immediately revealed on the map to enemy Outlanders. The Comm Station can also be used to buff or debuff the airdrop. For example, it can be buffed by adding extra loot and resources or debuffed by making it radioactive. A radioactive airdrop poisons the player that touches it with radiation, giving them little time to make it out alive.

In every Encounter, a radiation cloud sweeps the area after a certain amount of time. When this occurs, players have to be quick and evacuate before they die from radiation. If the player has the special consumable iodine, they can stay longer because of its protection. There are many consumables that Outlanders can take with them in to Encounters, each one serving a specific purpose.

If players survive the Encounter, anything they've looted will be added to their inventory. However, if they die, all of their loot will be lost, as well as any weapons, ammo and consumables brought with them. There is an option to buy Insurance in the lobby before the Encounter starts using Crowns. Having an Insurance will save the players from losing their loadout and items looted in the map upon dying.

A fast-paced solo combat where players spawn with randomized weapons, but can scour the map to find better weapons and take down other Outlanders. If players die, they will be respawned with a new weapon and ammo. Matches last 10 minutes and use a scoring system. The more Outlanders the players eliminate, the higher the score they get, with higher scoring players receiving better rewards.
