The only way to show the true horror of mobile suit war is to show it from outside the cockpit, where mecha stomp like Staypuft at a terrifying scale. The latest trailer for Namco Bandai's free-to-play Gundam Battle Operation focuses on ground combat, so Zaku have never looked more intimidating.
I like how this clip makes it look more like Earth Defense Force than Gundam. Improvements have been made since the beta, such as stun grenades for foot soldiers, visible enemy life meters, and more visible hit markers. The downloadable PlayStation 3 game features six-on-six Federation vs. Zeon combat, and hits Japan as a free download in late June.
