New unit - Ruby
Manufactured in the heavy factory. Ruby is a much heavier unit than others and is able to deliver a heavy impulse against close-by enemy units. It just has to get close to them first.
New unit - Cone
Manufactured in the heavy factory. Cone is a support unit meant against large groups, as it can only pull units from long range, which allows allies to push them away. It will not pull units that are already very close.
