I dont know any FPS that isn't a bit arcade-like for movement. My favourite is ArmA of course, since I can walk forward, but also look around (not cheating by using strafe), you know, like a person can. A lot of FPS games dont have that, including the ultra-immersive (except all the fine bits) SC. The reason FPS's are like that is because, in reality, our eyes and mind are doing a lot of compensating, for all the side to side/up and down movement that goes on while taking steps. Life, itself, "arcades" the view for you so it's not the jumbled mess it actually is. But if you watch some animals, even cats, as they sneak up on prey, their head is almost perfectly aligned with its target. Snakes are awesome like that too. People? People suck. The closest we get are like biathalon types, and even they have trouble, while breathing heavy etc, aiming to hit their target. Could you see a cat with a sniper rifle? They'd never miss.
Otherwise, the movement in Odyssey is really good, I find. You dont get caught up on object edges, where other FPS's that can happen. The reason we can change direction is should be the jetpack. Apparently even after jetpack is depleted, you can change direction by looking left or right and holding forward, but if you dont hold forward, you will not change direction while in a jump, jetpack energized or not. I have a feeling if the jetpack is depleted, you should not be able to change direction. Something else to add to their list maybe!
ED suits use shields, similar to the ships, and also have a high level of armour. It's so opponents have a chance to get away, but there are weapons you can shoot a couple times and your enemy is down. I havent tried walking around without a suit on but it would be interesting to see if you walk into a CZ with just the flight suit on, you go critical with one shot. If that doesn't happen now, add it to the list too.
