With the help of this guide you'll get all the 45 signs scattered across the game. Each chapter contains 3 signs the player has to get in a certain order (the second sign in a chapter is not visibile until you get the first, the same goes for the third which needs the second): some are pretty easy, some will force you to restart from a checkpoint or from the beginning of the chapter if you miss a step. The latter usually involves leaving certain enemies alive to juggle them later.

To "juggle" an enemy you just have to keep shooting at him and keep him flying until you reach your objective. The best tool for juggling is the machinegun, but sometimes you'll have to use your punches.

Getting all the signs unlocks the knife: despite its short range, this weapon will kill instantly any kind of enemy (except Brno) and ignores shields.

1 - In the last screen of this chapter, instead of jumping down to the next chapter, climb the edge on the left, duck and roll to a previous screen where the first sign is located.



2 - Just go back to the start.



3 - Move the box back to the elevator in the missile area and go up, then move the box to the next screen. Jump on the box and claim the sign.

Note: for the third sign you have to be careful to not kill the clone soldier shown in the image below



1 - Use the machinegun to juggle the clone soldier until he touches the sign as soon as you enter this area.




2 - Go back to the start.



3 - Go back to the area shown in the "Note" paragraph, you should find the clone soldier you spared previously. Use your punches to juggle him until you manage to land him on the wedge.

It should take a few tries, the image below shows the right position from where to punch him (more or less).

Now stay down and wait for him to walk to the next screen, then follow him back and forth until you can juggle him with the machinegun right into the sign. Pretty hard, wasn't it?

1 - Infirmary area, hidden in the dark upper-right corner.



2 - Go back and take the elevator that leads outside, right side of the screen.



3 - The last sign is located in the screen next to the one with the trapdoor you take to escape from the zeppelin.

Note: spare the life (for now) of the clone soldier stationed in the last story of the building.



1 - Clone area, just above Clone#57.



2 - Go back to the start, left side of the screen, partially hidden by trees.



3 - Use the machinegun to juggle the clone soldier stationed in the last story of the building.

1 - Ride the elevator and jump to the left at the right moment.



2 - Go back to the storeroom where you took the first box.



3 - Ride the platform and jump down at the right moment.

1 - Just keep going right until you get in this screen. You should spot its dark silhouette near the wall.



2 - Go back to the start, climb the star and jump to the left.



3 - Don't kill him right now.

Instead, sneak behind him, force him to roll to the left and then juggle him with the machinegun.

Note1: don't kill or brainbug him yet.

Note2: kill the one above but spare the one below



1 - Brainbug him and touch the sign on the left.




2 - Go back and brainbug the soldier we spared in the granade screen.

Keep running to the right until you reach the sign.



3 - Put yourself in the story above near the window (be sure to kill the soldier in the same story but on the other side) and keep spamming brainbugs until you get him. Then touch the sign.

Note: all the signs in this chapter are located in the second zeppelin.


1 - Enter the second zeppelin, jump down then walk to the right.



2 - Be quick: keep running to the right, the sign is just before the exit.



3 - I hope you have enough spare time to go back a little and get the third sign. It's just a bit to the left of the second sign.

1 - Upper-left corner in the screen with the Putzki statue.



2 - Lazer-Putzki screen. Easy peasy.



3 - Upper-left corner in the screen. You get there going right past the green key.

1 - This is a bit tricky: the sign is in the next screen, so you have to juggle this soldier to the other side without dropping him or killing him so he can walk alone to the next screen. If you try to juggle him only with the machinegun he'll die before he reaches the other side. So, you'll have to try to lure him near the edge of the crane, punch him and then juggle him a bit with the machinegun without killing him. There is a checkpoint in the next screen, so visit it before attempting any try. If you fail you can restart from there.

When you finally manage to juggle him to the other side you must get off the crane and drop in the screen below, or else there is a chance that the soldier will jump off the platform to pursue you (it actually happened to me).

Return to the crane screen and wait for the soldier to walk away, then slowly stalk him to the next screen. Don't juggle him yet because the sign is still outside of your view. Wait for the moment when he turns around at the end of his walking route, then start shooting until the corpse hits the sign.



2 - Go back to the start. These are my favorites. Use the roofs route to do it, since the scaffolding is too high to climb.



3 - Return to the screen where the first sign is and jump to the platform below to the right.

Now slowly walk to the edge of the platform, face yourself to the right and press the crouch key. If you are in the right spot you should be able to grab the edge of the platform like this:

Press the crouch key again to drop to the screen below, and there you are.

1 - Drop down from the duct, climb the wedge and jump. The sign is on the left, partially hidden by the wall.



2 - Go back to the screen where you have to stack 3 boxes to reach the duct, enter the duct and roll to the next screen.



3 - Near the end of the chapter, you don't really need all the 3 boxes. Just move one below the sign, climb it and jump. Or jump directly from the stack.

Note1: see this soldier, right at the start of the chapter? You'll juggle him later, so spare him.

Note2: leave the doors open. If you close them you'll not be able to get the second and the third signs later because the elevator stops working when you use the red key and you can't open the doors from the right side. Riding the elevator with the doors open without getting killed by the sentry gun is just a matter of timing: lure the sentry to shoot you (climb the platform and quickly get down), then take advantage of the long pause after a burst.



1 - I used a brainbugged soldier to do it, but you can use Hardboiled as well, since it happens during the normal course of the chapter.

Juggle the soldier until he's right above the sign, then drop him.





2 - Riding the elevator behind the green key door will lead you here. Lure the sentry gun to shoot you, wait for when it pauses and climb the platform on the left.

Roll to the left screen, the one were you should have left the doors open. Again, lure the sentry, wait for the pause then climb the platform on the left.

Go back to the screen where you got the red key. Stalk the soldier you spared at the start of the chapter, follow him to the previous screen and juggle him until he hits the sign.




3 - As usual: lure the sentry, climb the platform, roll in the duct and get the sign.

1 - Once your ally gets killed by the soldier, ride the elevator, kill the soldier, ride the other elevator and walk to the right to get the sign.



2 - Go back to the start.



3 - At the end of the chapter, on the left.

1 - Outside of the rocket, to the right.



2 - Outside of the rocket, to the left.



3 - Right after entering the rocket through the trapdoor, to the left, hidden in the shadow.

Note: all the signs in this chapter are hidden in the shadows, so they're a bit hard to see.

1 - After defeating Brno, brainbug this soldier and grab the sign.




2 - Ride the elevators to the top when pursuing Putzki, stand near the left wall and jump.



3 - Brainbug Putzki and go outside of the rocket. You should see the sign's dark square silhouette above the exit.
