If anything was iconic about the first game, it was how they handled the HUD, but I guess the parts you can show off are the visor and how they handled the laser beam.
Personally, I think it would be fucking awesome if they went Aliens on this sequel and did make it more action packed because you're now more prepared for the threat. They made a big deal about how in the first game you were using worker space suits and tools to fight off the enemies. There were military weapons, but those too weren't designed to fight off the monsters. Assuming this game takes a good bit of time after the first game, it would be cool if the new weapons were designed to fight these monsters. The suit in that picture looks straight up Iron Man in parts.
