Here is a list of the game modes currently available in Survarium. In each of those two teams of 8 people fight one against another.
Battery Retrieval. Containers with batteries are randomly spawned on the map. Teams need to find and bring the containers to their bases. The winner is the first team to collect all containers or whichever team has more containers at their base when the allotted time is up. It is important not only to locate and recover the containers, but also to prevent the enemy from capturing them.
Survarium also has a variation of this mode in which the containers are not scattered randomly on the map but spawn in one of the three devices placed on the location. The teams must find out which of the devices has a charged battery, and then recover it.
Research. The task is to take control over units for the research of anomalous activity. Capturing and holding a point awards your team points towards research success. The winner is the first team to complete the research of anomalous activity or whichever team scores more points in the allotted time.
Team Deathmatch. A classic team vs. team mode for shooters. The rules are simple: kill enemies and try not to get killed. The winner is the team that scores 100 kills first or has more kills in the allotted time.
Artifact Hunt. Two teams fight to acquire a rare artifact called Radiance of the Forest which spawns at a random location on the map. The team that finds and delivers the artifact to its base scores a point. The first team to score 5 points wins. Or, if the match time runs out, the team with more points wins.
