S.U.T.A.Beta 2 is an action survival roguelike shooter with elements of strategy. In Classic mode, your goal is to survive until help arrives, while Rogue mode is simply about surviving until you eventually die.
And, yes, this version was made in Scratch and still functions on it (even after the recent large update). But don't let that fool you, as that doesn't prevent it from being a very fast-paced and challenging game. The full release will be developed in another engine, but I still think this is one of my best solo projects (though very basic).
