4: We have all had our hands busy, but if you could give some more info on what you mean by "Gameplay Style" of Contra? Like, having more tech buildings density on this map, which makes map control more significant?
Yes and also include terrain features that make it ideal, for example, for artillery to fire from or have stealth units plan an ambush. Maps that are built for the Contra mod.
Some maps are horrible to play Contra on if you haven't noticed. It would be a great touch to add a couple of official 3v3 or 2v2 maps in future versions whenever you guys get the chance to create them. Hostile Dawn gets kind of boring after a while
