This quest involves collecting weapons for General Freewheeler. He is located in the Main OTAF Base in Avalon, the quickest route is to head south from the Camelot grid exit or, even quicker, using the Fixer Grid.
Once inside, you can find the General standing at the Southern end of the base in his shiny Omni-Tek Armed Forces uniform.
If General Freewheeler isn't around, it just means that he's taken a quick trip to reclaim. Just hang around for 5 minutes and he will return.
After a quick chat he will hand you A Dimension Crushing Storage Device
These can be found from the regular mobs in the Sentinels base in Wailing Wastes:
Fly south-east from the Main OTAF Base, zone into Wailing Wastes and head eastwards. Beware that there are plenty of aggressive mobs inside and quite a few high level mobs too. The quickest and easiest targets to focus on are:
Also be sure to be on the lookout for Omni-Tek Bravery Tokens while you are collecting the weapons, these give you one extra token and drop quite frequently from these mobs.
At this point he will ask you if you would like one of the "Tower weapons" which and give you a A Note to Supply Master Eel, depending on which of the weapons you have collected.
Note that this is completely optional and only required if you wish to build one of the Advanced Notum Wars Turrets.
Currently the turrets you are given for the M150 N.A. Booster Edition are not ingame.
If you wish to get one of the tower weapons, head North-West from the Main OTAF base to the Secondary OTAF base
Just inside you can find Supply Master Eel who seems like quite a busy man.
However he will accept your Note and hand you the tower weapon.
Below is the list of tower weapons you will receive depending on which weapon you have collected:
