It definitely augments his durability, although strength remains unclear.

No. It was never implied that it did. I'd assume it's just armor unless there's further information.

Well judging from Homecoming, when he had to operate during the latter half of the movie without his suit, I don't think so

Actually you bring up a interesting point. Shouldn't his suits be bullet proof? Not saying Spider-Man should stand in front of bullets but since Tony made the suits, he'd be a dick not to make Peter's suit(s) bullet proof.

Yeah. Logically it should be considering even the first suit he made in the cave("With a box of scraps")was bulletproof.

I don’t think so, but it makes you wonder what the instant-kill mode does.. unless that was just played as a joke(probably)

Its armor so makes sense to increase his durability and striking outside of that no unless its been confirmed

I would assume the instant kill mode would be a targeting function with kill shots like hitting weak spots to kill an enemy. Other than that I don't think it boosts stats.

@seagod: so essentially the suit would be in control or would it just suggest where to hit for critical shots? And wouldn’t Peter still control the strength/force behind it?

@dannyphantom: Peter would be in control but I would figure like in the boat scene there would be markers on his vision that said where to hit, shoot, and maybe even a order of who to take out first.

It's meaningless if you have a high-tech suit but it not enhanced your power.

So yeah,I'd say it increased his strength and other stats.

I agree.

It does not augment his strength. It might augment his durability, but we have no proof of that.

On a side tangent, why did the reformed arms-dealer Tony Stark who didn’t want to make weapons anymore because of all the death, create a kill-mode in a teenager’s superhero suit

For both we don't have evidence. From what we've seen it seems like it might augment his durability but not exactly his strength.

The Iron Spider does.

The Iron Spider, I'd say so, but not his other suit.

@seagod: yea, but then why call it instant kill if peter won't ever actually hit anyone with enough force to kill them? And like post #15 said why would tony even create a function like that in his suit to begin with? idk it just doesn't make any sense to me, it feels like it was just there for laughs

@dannyphantom: I think the function is more of a hope for the best but plan for the worst. Tony hopes Peter wouldn't be placed in a situation where he has no choice but to kill but he also doesn't wanna leave Peter without some help if worst comes to worst. As for Peter not using it well remember Peter was still under the training wheels protocol. So by the time he would have unlocked it Peter would be older and more mature and ready to make such a hard decision for the good of the world.

No. I'd say the Iron Spider might increase his durability a little bit, but nothing else - though there are no feats to show that anyways. The regular suit doesn't increase his physicals in any way.

Durability obviously since all Tony's tech has cushioning, he could be bullet proof too since Tony was worried enough to install a parachute incase Spiderboy stupidly managed to fall a fatal height so why wouldn't he have some sort of precaution against bullets too?

Instant kill mode probably amps him?
