This guide will show you how to get the Christmas 2014 achievement (survive 4:30 in the Christmas 2014 survival map) the easy way.

Please note that you will still have to shoot at enemies, which I guess, makes this way less of cheat? Whatever.

Step 1

As soon as you spawn go to the center and grab an ammo bag.

Step 2

Immedeately after acquiring the ammo bag turn right and run behind a small house shown in the two pictures below.



Step 3

Position yourself as close to the wall as you can and hold down your crouch button. The best position is displayed in the image below.


Step 4

Survive.

Most of the enemies will ignore you.
From 0:00 to 2:20 you only have to worry about some flaming marsh hoppers, about 3 kleers and 3 kamikazes.

From 2:20 and onwards Zorg Mercenaries will start to spawn behind you. This means you will have to turn around and shoot them as soon as they spawn. You will hear their distinct sound once they spawn, so it's not hard to keep track of them.

From around 3:00 kamikazes will start spawning from the initial direction you were looking at. You have to prioritize them over the Zorg Mercenaries.

I recommend using the XL2 Lasergun up until the kamikazes start spawning, then switching to the Thompson as it has less of a projectile hit delay.
