The focus of work in the last few days has been replacing the existing placeholder combat system with something that would support all the features we wanted. I'm pleased to say that the work is now complete (minus some little polishing work and projectile impact effects) easily supporting many hundreds (actually I've not reached an upper limit yet :D) of different types of simultaneous weapon blasts in the world at a time.
These blasts can now miss, hit friendly targets or damage and destroy parts of the world as well as enemy kill units. Currently there are four different weapon types, a standard and heavy damage version for both friendly and enemy units, with plenty of scope for more to be added in the future! Also planned is to distinguish weapon types by rate of fire but this is planned for the next build. Below is a video showing the changes. Let us know what you think in the comments :-)
