What We Are from the Future 2 is
You're a student historian arriving in Ukraine to reenact a WWII offensive, muddy boots on broken ground, and then your mock battle gets swallowed by real shells tearing through 1944. The uniform on your back isn't a prop anymore. Across the smoke, a T-34 crests the hill like it owns time.
