This is the first time I have seen someone give animations to the static water in AOK and its very well done.The concept is brilliant to use the fish animations as a base to give moving water giving the HD feel to the old game.Since this just modifies the water you can use this in your normal game without any issues to the other units.
Instructions for installation is provided and creator has given on instructions on how its done.
Down side is that all 3 water types are replaced by the same movement of water and the movement itself is not that top quality as it uses original water parts by the looks of it.and the water animation stops at the shore line so looks a little odd.
Additional Comments: Extremely creative mod that adds variety to the original game like HD. Highly recommended to download.
