So, speaking of biotech mecha....any chance GH2 will ever have an alien faction show up? I'm thinking Zentradi-style, but I'm wide open to anything. I just like the Outside Threat as a plot device/excuse for high-powered combat/loot. Robotech, Warhammer 40k, Battletech, Earthsiege, it's a pretty common staple. Although I'm pretty tired of the 'warring factions band together to face the common foe'. I'd rather things turn into a 10-way brawl.
ZOMG. Someone could totally use Arena mode to make X-Gear-Com. Not me, too much on plate already. But I could totally see that. It seems like it'd be easy to write in a 'research tree' of sorts in the form of reward flags like the shops/skill trainers. And of course mission results can be fed into the same sort of story count variable to determine whether to move on to the next wave of aliens, or if attacks slow down. Hmmm.
