@Malice: Thanks! Well to be honest I didn't think about that yet. I guess it'll depend on the map how many units can be dispatched. Theoretically there's no limit of units on-screen though the space is limited because a map is for example 20 by 20 tiles large ^^.
And update: I added some cinematic-camera-effects and reworked some animations. TacticsProject #6
and here's a video of the main menu. here's where you'll manage euqipment and skills of your units. it's not finished yet, but it's almost complete.
