A few features that have been added to Eclipse in the past month or so:
AoE ground selection:
A system for selecting the target for an area of effect spell. It creates a decal (of scalable size) that follows the mouse around, and spawns spells in the selected area.
Summon selection and orders:
Selecting multiple units and issuing commands for them to follow. Almost complete, just a draggable box for selecting a group needs to be made.
A few spells have been coded, but the Ice Cloud is the only one with complete (or at least, very pretty placeholder) models and particle effects.
