Jagged Alliance Online: Multiplayer Modes

Each PvP arena has its own lobby and rankings. An internal ranking system (ELO style) was created for the matchmaking system to determine a player's strength based on a variety of factors such as the mercenaries' level and position in the rankings. This helps reduce the amount of unequal and unfair duels.

The modes:
 Deathmatch: Direct battle, mercenary versus mercenary. The player who is still standing at the end is the winner.
 Bounty Hunter: Who can sneak around the target's guards or take them down best to be the first to eliminate the NPC at the end?
 Search and Destroy: Both players have three objects in this arena. The aim is the destroy the opponent's object while protecting your own.

The arenas:
 Deathmatch #1: North Africa - A warehouse with narrow alleys means fast-paced action on the battlefield.
 Deathmatch #2: Long corridors and narrow passages provide plenty of tactical diversity in this Central American missile base.
 Bounty Hunter #1: Who will be the first to find the drug baron in the South American favela?
 Bounty Hunter #2: Italian blood is being spilled here. Who will be the one to claim the bounty for the general?
 Search and Destroy #1: Morocco - A windy canyon with a bridge in the middle is quite a challenge for both teams.
 Search and Destroy #2: Two abandoned military camps in the midwestern United States that are both under attack from rival mercenary teams.

Battles in Jagged Alliance Online are turn-based, so the length of each turn plays a special role. Players that complete their round especially quickly receive a percentage bonus on their mercenaries' action points in the next round. So in certain situations it certainly makes sense to make decisions quickly for strategic purposes.
