Jacobs Rest 7 in 1 completed (brutal onslaught hardcore ff, all alive)
A challenge called "Campaign Execution" was used to simulate campaigns being completed from first map to last with all ammunition and health being carried over from previous mission to next mission.
The challenge works like setting checkpoints after each mission. If you fail a mission in the middle of the campaign, after restarting you will still have the carried over equipment from last mission. In this run specifically we have never failed a mission, thus this counts as an official completion of 7 missions in a row. (An actual map of jacobs7in1 can not be easily made due to engine limitations)
Extra note, the server we played on had an older version of the challenge installed. In the older version, it was not taken account how many marines were present in only the first mission of the campaign. Throughout the whole run we should have had the difficulty settings of only 3 marines being present in the mission. However, as we progressed through the campaign, more people joined and tried to play. Which means it was unintentionally a little bit more difficult for us, with some missions having the difficulty settings of 5 marines and some missions of 6 marines. In the new version of the challenge this is taken into account and no matter how many marines are alive and how many marines were selected, the difficulty setting would be that of 3 marines throughout the campaign.
