The expected first person shooter modes are here, along with a few unique modes.
Deathmatch[]
A free-for-all scenario where the winner has the highest amount of points. The loose structure and simple objective of Deathmatch makes it playable on many maps and with an odd number of players.
Duel
A two player Deathmatch. Commonly played with Xonotic Pro Mode rules set with power ups disabled as standard rules are less fair to the out-of-control player. As there are only two players, map control and tactics have a greater importance than in regular Deathmatch.
Team Deathmatch[]
A teamplay mode awarding points to a team for each frag its members scores. Map control remains as important, but co-operation within a team opens new tactical options.
Capture The Flag (CTF)[]
A teamplay mode focused on capturing flags. Though there are no formal assignments of roles within a team, typically it is played with a structure of a base defender, mid-fielder, and base attacker.
Complete The Stage (CTS)[]
A mode focusing on the nuances of movement and physics. Though fragging is not the objective of this mode, explosive weapons such as Devastator, Mortar, and Hagar may appear as tools to complete the obstacle course. The majority of custom maps are designed for the (Xonotic) DeFrag Mod and may be impossible to finish without.
Clan Arena[]
A round-based teamplay mode awarding points to the team that survives the round. Item pickups are absent and all players spawn fully equipped with maximum health and armor, thus shooting effectiveness and team coordination are the emphasized skills.
Freeze Tag[]
A round-based teamplay mode where killed players are instead frozen and can be revived. Similar to Clan Arena, ammo pickups are absent and players spawn fully equipped with maximum ammo, but the starting health and armor is the same as other modes. With the added concept of reviving teammates a team can make a full recovery within a round.
Keepaway[]
A free-for-all style mode where frags are centric around a ball. Conceptually similar to Deathmatch with the added condition that acquiring and retaining the ball is necessary to earn points. While the amount of time a player holds the ball is tracked on the scoreboard, it is not directly related to the number of points s/he receives.
Nex Ball[]
A football, or soccer, style teamplay mode played in third person view.
