A brand-new battlefield awaits!
One month after the third Squad Jam, Karen Kohiruimaki is starting to consider her options outside of GGO...but fate wont let that happen! Out of the blue, past prizewinning SJ teams receive invitations to playtest a GGO game mode with an all-new objective: capture a base defended by hyperadvanced AI NPCs. As Llenn reluctantly agrees to participate in the hopes of fulfilling her promise of a rematch with SHINC, she cant help but wonder: Just how challenging can these AI NPCs possibly be?
