Challenge matches can be accessed via the main play screen. To enter a challenge match, you’ll need to be the leader of a party of five. Select the Challenge queue, enter a game name, and select a server. Once that’s done an opposing party can select your game from the queue, starting the match.
The Experimental Queue adds two new, more casual modes to the game:
Assault Mode: Instead of having to capture points, Siege Engines will continually spawn, alternating between teams.
Capture Point: There’s no Siege Engine or push phase. Instead, teams will fight each other to be the first to capture five points.
Fixes and small changes also dropped with Patch 11. For a full list of changes, head over to the Paladins forum.
