One thing that a lot of players miss about NS1 is the ability to drop a second commander chair in an obscure location on the map. I am not sure why the developers have strayed away from allowing this, but I have an idea.....
What if there was an upgrade on marines that you could research through a robotics factory (Or through the command chair itself). You could build a mobile unit which would unpack into a command chair (Think command and conquer style). This unit would move relatively slow and have to be escorted stealthily to a strategic location. It can then build into a CC and be used as a second base. You would need the robotics factory to build the mobile CC, and perhaps you'd have to research the robotics to upgrade to mobile CC ability like with ARCS.
This option wouldn't be possible or viable in early game preventing random CC relocations, but would allow the option once marines have the res and map control. It wouldn't be very hard to implement and would be pretty amazing in my opinion.
This would be a counter to the EVER PRESENT cc rush by skulks when the marines have pretty much already won. It get's old having to drop CC's in OBVIOUS locations so dropping a second CC to counter a skulk rush isn't very viable vs good players. The mobile CC could be a genius backup base that is hidden.
This is simply my plea to the developers and the community to look at the positives of CC relocations and to consider adding them back into the game. I realize my idea won't be implemented but it could be modded.
I also am waiting for an official response from UWE as to why dropping CC's outside tech points is not allowed. My theory is that the game engine isn't streamlined enough to allow for it, so the developers have strayed away from this to prevent more bugs and possible exploits. Band-aid alert? My answer to that is to make the game less buggy and able to support more dynamic play.
I assume the excuse for not allowing it is for "balance", but I don't personally see that as good enough. You can already relocate to any tech point, so why not bring it to the next level and allow for more freedom?
