Some snippets of info from the latest issue of Nintendo Power…
- game world feels more alive in current build, gives the impression of a massive alien attack
- stores with TVs show news reports of attack
- helicopters are shot down by alien invaders
- enemy AI tweaked, now more intelligent
- story has an X-Files vibe
- removing the HUD will add in some other environmental/personal indicators to help you out with health and ammo (heavy breathing, color changes for damage taken, and more)
