Attacks in combat cause damage again, and now they're using the skill chain system. Currently, the first tier of an attack causes 0.5x damage, second tier causes 1x and third tier causes 1.5x damage.
I've also started a working on the game grid. I've added grass tiles, and humans and zombies are randomly being placed on the grid. It looks neat, at the very least.
Next steps: path finding and attack ranges.
I've got a ridiculous headache, so I think it's best if I cut this short.
