Multiselection!

Implementing multiselection has been something I've avoided due to Archrebel's tactical nature and its deep roots in Rebelstar. I've always told people it wasn't going to happen. However, after playing the demo, I realized there's considerable potential walking time in the game, especially considering how much larger the maps are compared to Rebelstar.

With the UI part out of the way, it is now time to figure out an algorithm that is capable of identifying which tiles are the appropriate ones to move the selected units around the destination tile. Boy... this is going to be fun...

Stay safe!
