No, la challenging, per come ho capito, cambia il finale soltanto:
Right after the APC blows up, everyone will see their gear set items drop. These gear set items are gear score 214.
As soon as you see the items drop, THREE members of the group must exit the game immediately.
One member MUST stay behind and wait for the rest to reconnect.
When the three members return, their backpack will contain one gear set item with gear score 240. They will also be rewarded with 40 phoenix credits.
The one member left behind will not receive the phoenix credits or the 240 item. The group should cycle who stays behind on every turn.
All members can now collect the drops left behind near the APC by teleporting to the player left behind.
