“The battles that follow aren’t typical of most first-person action games.”
Warfare History Network
“an incredibly fun and long lasting game for any war gamer or history buff. ... you’ll still be playing this months, or even years, from now.”
8.4/10 · Game Chronicles
“it’s remarkably compulsive. The concept and the individual challenges are unique, and the sheer difficulty of it makes riding a tank for 20 miles peculiarly rewarding. ... there’s nothing else quite like it.”
