Unreal Tournament 99 Guide

UT 99 has the following requirements:

  1. Needs 5 sequential ports (game port + 4 next ports), plus an additional webserver port. AMP can’t at this stage guarantee the ports are sequential.
  2. Uses an AMP-supplied config file (_AMP_UnrealTournament.ini) that needs to be used instead of the default UnrealTournament.ini). This is to ensure that any user changes to the file are not overwritten on later updates.
