Those aren't moa... they're chocobo! nerdy trolling aside, thats actually cool that theyre doing this, it makes it seem less like humans are the only thing the war effects, kind of gives you a grander sense of the scale of things.
yeah that'd be sweet, just scare all the wildlife and have it bum rush the Covenant, i bet (like the Zoo in New Mombasa) you will find area's where the covenant just killed all the animals.
MOAS... IN.... SPAAAAACEEEE~!!! actually until I have a clue of the campaign, meaning like three months after I get the game and wanna take a break from forging will I know where and how many there are of these things.
