It stings me to see all those new people asking about the 'Can I do this in the game? That guy did it in the trailer."
Ok, here we go.

You cannot:
-Carry a sniper rifle
-Shoot a one hit kill
-Carry dual weapons
-Perform a roll to break a fall and continue going
-Rudy a rocket
-Fire a rocket (no rocket launchers)
-Turn vault a ledge(?) (This one I'm not sure on)
-Kong to 180 to draw dual Auto-pistol to back slide to shoot an Anger chasing you then backroll to a 180 and keep going
-Wield dual swords and stab through rusty containers (no penetrations)
-Shoot both sides when carrying dual weapons, just think about how to put it into game controls for PC and consoles(+ No dual weapons)

You can, however:
-Use a short rifle with a scope attachment and think of it like a sniper rifle
-Carry molotov
-Slide to break a fall
-Shoot while in a slide

Please, add anything I've missed and correct me if I'm wrong.

You can use a slide to break your fall, its in http://www.brinkthegame.com/features/freedom/ video, labeled "slide to break fall"

There are no dual weapons in the game what-so-ever, nor melee weapons, with the exception of a knife that can be used with a pistol. But you CAN fire while slide tackling, not sure if it can be done backwards though.

Also, wouldn't it make more sense to just say "there are no rockets in the game"?

You can't shoot or stab trough anything. No bullet penetration through any objects.

Also, please add that there are short rifles which you can equip with a scope.
And, make a notice that they put molotovs in (because in some videos they said they took 'em out, but they're back)

You can operate cranes Or at least repair them and turn them on, so they can move things (Not sure about dropping things on people though)

It's a fixed animation, because it's part of the objctive. You can't move vehicles like in driving or operating.

technically, you can probably get a OHK with the short rifles, under certain circumstances.

- If you have a damage buff on and you shoot an unbuffed Light, there's a pretty god chance you will kill him in one hit.
- If you shoot an enemy without full health, there's a good chance you will kill him. You could say that this isn't a OHK, but if it was the first (and only) shot you put into a guy, and he died, you just killed him with one hit.

Yea but the enemy didn't die from just one hit. Using your reasoning you could use a pistol and get a OHK, enemy low on health one shot from my pistol OHK.
So No What you described is not a OHK, the second point anyway. The first is unlikely to happen/be possible.

I think you would need to shoot an unbuffed light in the head with a buffed short rifle to get that chance.

I think this as well. That's how I understood it.

You can't wave into a person's sniper scope then one shot them in the head.

You can't put someone to their knees and dramatically shoot them in the head with your revolver after spinning it's barrel.

You probably can't drop large debris from cranes onto the battlefield (maybe would be cool but highly unlikely)

You cannot customize your bullets/grenades and write on them Jah Lick Them With Thunder (Pause the trailer and read it)

You cannot destroy an entire building with a molly.

Can't take off hoods/facemask mid battle to look awesome.

Cannot instant death facestab... unless they pull a Valve

Cannot open doors (pretty sure anyway)

Cannot OHK with a revolver.

Cannot check enemy pulse to see if they are alive (around 2:45)

Cannot destroy the enviroment (Around 1:27 guy on the run shoots a bridge and breaks it)

Cannot kill someone and then have the game's logo pop saying revolution begins. (just for fun :celebration:)

Did I miss anything?

You can't come out of a direct grenade launcher hit undamaged, on your legs, ready to shoot the [censored] out of someone with a minigun only seconds later

And hopefully it's a Tier 3 weapon buff.

Lol I can see it now, Everyone chasing after teammate engineers that can give out tier 3 weapon buffs. Consent Buff me please from teamates lol.

so... the trailer for the game has a bunch if awesome stuff the game doesnt even have. sounds like most game trailers actually.

Maybe you can have a buff or perk that'll let you have half a chance at avoiding the grenade knock down if you're a buffed soldier heavy.

According to the devs exact words:

"Rifle butt melee (basically anything but pistols) is a knockdown, same as excessive splash damage."

source - http://www.splashdamage.com/forums/showpost.php?p=237537&postcount=9

Until we can clarify what exactly is meant by "excessive," saying that a nade will knock you down is purely speculative.

I wish we could bug the splash damage studios and listen in sometimes so we could know the answers to half our questions sometimes.

Switvch to operative class, kill a member of the cafeteria crew (not the SD staff, we still need them) And interrogate. Voila, there is your answer.

Wait wait wait, interrogating does only work on knocked down people.

works on "downed" people, not "knocked down". Big difference

Well ... we know it does work on downed; but do we know if it doesn't work on knocked down-ed ones as well?

lol yep, a melee or a few bullets to the face. :gun:

So... the point of this thread is... you can't be a bad-ass?

What a bummer... :gun:

maybe a medic threw that heavy a syringe.

You can still be bad-ass. They removed some things or didn't add certain stuff because it didn't fit in their philosophy. (f.e. dodging rockets like in the trailer is not in because your screen would turn around, making it hard to aim)

This thread is pretty usefull, because it takes away a lot of misunderstandings.
