Now that we have beaten the Witness, I think a new mode for reclaiming the system, what ii call "Reclamation", would be a fun idea. Think a horde mode in the same vein as Onslaught, but more in depth, with more buildables and maps, and a full on endless mode. The maps could be on rotation, so one is the focus each week, giving more rewards and being more difficult, but still with the other maps available. We could have maps on Neomuna to try and deplete the Shadow Legion, one on Europa to deal with House Salvation, one on the Moon to finally retake it from the Hive, etc. Im also thinking more defenses, player-manned turrets, buildable walls and fortifications, traps etc. Onslaught was good but its held back by being a stop-gap activity, with only 3 maps and limited replay ability, and this new mode would give us the feeling of finally being on the offensive.
