Bosses

There are twelve boss fights in PSU's Network Mode (eight original, and four extra in Ambition of the Illuminus). All are currently accessible in free missions, with the exception of Dark Falz, which is only freely available on the Japanese PC/PS2 servers from Seal of the Dark God. However, the boss was accessible during the Maximum Attack G event for all servers via the Program DF mission. Once the Program DF' mission is released, all bosses will be playable once again.

The same boss can show up in more than one mission. Below is a chart that shows where all twelve bosses can be found:
