Hey there!
Last night as I was lying in bed I started to think of ways that I'd like to see the battles progress in Guns of Icarus Online. Of course I had all kinds of fantastical ideas that didn't really make sense, but I did think of one I thought was implementable: Tower defense.
In Skirmish there would be a central platform with three levels, where a team of four would defend from various hardpoints against an attacking force of two ships. The top would have four to six light hard points, the middle four to eight light and heavy, and the bottom four light, but with arcs that could face straight out and to the bottom. The tower can have more people if there are more ships, so 8 on tower versus 16 on attacking ships. The tower would have a heavy layer of armor over various sections that would work like ship armor; rebuildable and once down, the tower itself takes damage. The attacking force would have a set number of ships, whether it's a total amount to pull from, or each ship only gets two lives or so. But I think great strategies could come from this, as well as epic battles.
In Adventure mode it could work either way, a fleet of PCs versus NPC tower or vice versa.
Any thoughts?
