I have created several new actors for the campaign mission in my next mod, but most of them only have placeholder sprites. Drawing proper sprites for these actors is most likely quite easy for a decent spriter, but I don't want to spoil the mission by giving out too much information here so I can only give detailed information about one actor. The droppable SAM site (see gif below): Comes in its own drop crate that use thrusters to decelerate to a safe landing speed. Automatically engages air units with homing AA-missiles. The crate will also be used for another very similar actor, that also need sprites.
My previous missions can be found here and here if you have not seen them.
I appreciate any help I can get with this. If you are interested or just have questions about the details, don't hesitate to post here or send me a PM
