PvP

Player vs. Player, colloquially shortened to PvP, is a game type that currently comes in the form of Duels. It is vastly improved on Update 10 with the introduction of Conclave.

Duel
Dueling is a game mode added with the introduction of the Clan Dojo. By building a Dueling Room in the Clan Dojo, two players in that Dojo can begin a duel session. During the match, most of the effects and damage dealt by Warframe powers and Weapons remain the same as in missions.

Conclave
Conclave is a Syndicate that provides large scale PvP missions. First introduced as a game mode in Update 10. It was restricted to players with similar Conclave Level instead of their clan affiliations, and features battles on designated arena tiles. The new Conclave introduced in Update 16 creates a new Arsenal for players with a limited number of Warframes and Weapons in order to allow fair play. Currently, Cephalon Capture is the only game mode available in Conclave. This mode allows Tenno to earn Standing from Teshin, and unlock unique rewards as a result.

Solar Rail Conflict
Solar Rail Conflicts take place on Dark Sector nodes that are contested by another Clan or Alliance. Introduced in Update 14, this game mode allows a total of eight players compete in an asymmetrical attack/defense gamemode, where four players (supporting the Challenger) attempt to infiltrate and damage the Solar Rail while the other four (supporting the Occupant) defend it.

Available Equipment
Conclave and Solar Rail Conflicts currently only allow a very small number of mods, warframes, and weapons, to ensure balance is fair and even. Prime, Wraith, MK-1, and other unique variants are permitted.
