This game is basically Cossaks but with World War 1 sprites. The UI is horrendus and the game is not optimized for modern OSes. However most of its flaws are inherit with Cossaks and the other games using its engine such as Conquest of the Americas, as all of these games suffer from the same graphical glitches and poor optimization.
The Art portion of the game is fantastic, if a bit dated, but you can tell a lot of care went into the artwork for the individual vehicles, soldiers and buildings.. Sadly they went really cheap on UI and it shows.. This UI is just terrible!
Gameplay wise, its Cossaks. I wish there were trenches in the game, sadly there are not. However this doesn't deter you from just spamming bunkers, outposts ect to create the illusion of them. And artillery is an absolute blast to use in this game, more so than in the previous Cossaks game.
The AI works pretty well. Though it does annoy me that the formations system from Cossaks has not translated over to this game, meaning most of your armies tend to just form massive blobs of death.
Not bad for $2 though. You get what you pay for really and I think the game is priced very fair for what is on offer here. You'll get a few hours of enjoyment out of it. But if you already own Cossaks, you'd probably just stick to that.. This game isn't anything you haven't seen already.. granted its got Planes and Tanks.. which is pretty cool and all.. but mechanically they're not that crucial to the game. They still play like any other artillery or cavalry unit, just with more HP or faster moving.
