[Discussion] More structures in unowned rooms

Davaned

I think that it would be interesting to have more of a concept of investing in an unowned or reserved room. Anyone have ideas for types of structures that would make sense? In particular structures that only exist in non-claimed rooms.

Outpost limited spawn with the ability to recycle or renew (reduce max TTL each time) or even heal inefficiently.
Palisade Weak walls that block movement or have huge fatigue for all units and decay like ramparts.
Sentry Range 5 tower-like structure that can attack
Watchtower Provides vision of adjacent rooms at the cost of energy per tick.

The idea of combat engineers that create things on the battlefield or setting up skirmishing outposts now that we have power creep harassment seems interesting. With the addition of the mysterious factories, and the pull ability it would be cool to have special buildings that you can drag into place.

Also, siege specific non-creeps that you bring with you would be very interesting. Things like

Siege Towers Lets you bypass a wall, needs to be defended.
Battering Rams Let units not adjacent to wall use their work parts to damage wall.
Forcefield Reduce incoming ranged damage in a small region with a constant energy upkeep.
Undermine Able to slowly construct a tunnel through a wall, let you bypass incredibly high strength walls if you can successfully complete it.

One of the most complicated parts of maintaining sieges in real life is the supply chains. Making it so that there are ways to attack that involve something more complicated logistically than sending streams of units to slowly damage walls could be interesting.

I like the buildings idea, though I feel they should be at the level of low boosted creeps. Powerful against unboosted, but not really going to hold back T3s for long.

I don't think Siege weapons work with the way that rooms work in this game. If you were guarenteed more space between the edge of the room and the wall it could work, but if they're actually useful people will just build walls around the edges and make them very hard to deploy.

I like the Outpost and Palisade idea.
Could be constructed in owned rooms and dragged into place to be "unpacked"

The ability to renew creeps and vision is IMO worth the work.
It should have a really rapid decay (5E sec?) so that maintenance cost is high and maybe 1000 shared res storage.

Once you have a Outpost you should be able to build Palisades in that room.

Renewing creeps is (at least was) planned for the Commander class of PowerCreeps, which I think is actually a more suitable place to have it. I'd love to see it happen Might actually be a reason for me to invest into PCs more.
