Red Storm 2: Survival A damn shame
I'm not aware if the original Red Storm came out before the first Robokill or not, regardless, you have not made a worthy competitor. The multiplayer is unplayable, a lot of the upgrades you have to purchase with real money are standard in Robokill, and there doesn't seem to be any originality or improvement on the levels.
I'm not the type to judge a game because of its similarity to another or for microtransactions (for which I'm not a fan anyway,) but I don't see any real improvement over Robokill (which also required cash money for in-game items) especially anything worth paying for.
Get more creative with the missions and the level layout, balance the microtransactions better, and fix the multiplayer and you might have yourself a customer here with your next game.
And so this isn't entirely negative, controls worked fine single player and the graphics (although not varied enough) were pretty cool.
