I'm curious as to how the bow will function in multiplayer. I'm talking about Instant Action, Crash Site, etc.

Will the bow be a primary weapon, secondary, or a "grenade" type?

If it's a primary weapon, they would have to provide you with a lot of arrows, like 10. If shock arrows, airburst, and explosive arrows are in, I would assume that they would function the same as an under-barrel gauss attachment or grenade launcher attachment, and you would only get a few shock arrows which would probably drain an enemy's energy, and possibly immobilize them for a moment. The explosive arrow would probably just be the one, like how you only get one under-barrel grenade launcher round.

If it's a secondary, you would probably only get like 4 or 5 standard arrows.

If it functions as a grenade type, then I can see you only getting one arrow. But if shock, airburst, and explosive arrows are in, why would anyone pick the standard arrow over those? Unless you can only equip an explosive arrows as your grenade type if you've already selected the bow as your primary or secondary weapon, whichever it is.

Also, there's the question of draw strengths. I saw in a video that the guy was talking about there being different draw strengths to your bow, so the more you draw the arrow back, the farther it will go and the more damage it will do, but it will also take longer to fire and drain more suit energy if you're firing from cloak. He also said that the bow won't be an insta-kill unless you hit certain areas of the body (chest, head).

Do you guys have any more information or speculation about the bow in multiplayer?

They said the bow is part of the suit so it's always available, though that's probably just for the campaign. Still one of the pre order bonuses is unlocking the bow at day 1.

i was thinking about this too.
in campaign i think it is available all the time(once unlocked)not sure about multi.

i don't think the electro shock arrow is in multi, i think it would be overpowered. too much water about??
in hunter it's 1 explosive and normal arrows(no amount confirmed)also air burst but don't know how many.
there are also other arrow types but no mention of what they are yet.

That makes sense for the campaign, since you're not going to find another bow on the ground anywhere, so they don't want you to get rid of it. Although, where are you gonna find extra arrows? o_0

And if the bow is its own independent weapon, aside from a primary, secondary, or grenade, where are they gonna put it? There's no more buttons on the controller to work with. That's why to switch to grenade you have to double-tap the Y button. Maybe it would just be a third weapon you'd have to cycle through, by pressing Y again. Or maybe you'd have to hold down Y. Who knows?

They should let you pick up used arrows like in Metro 2033

You can, check the gameplay videos from the dambusters demo

Though in case you meant in MP it's probably not going to happen because bodies dissapear pretty fast
