You can purchase Armor for 500 Jolts, and every time you have to re-buy Armor it costs more Jolts. Armor will save you from being downed 3 times. After the 3rd time your armor is depleted and you have to purchase more at an Armor station. Armor is downstairs near the STG44 wall buy.

Nice thread buddy. Also there is an extra little easter egg. When the player/players reach round 50, a Brenner spawns in with a lot of health. You actually don't get anything from killing him, I still just like the fact that they put him in there for us higher round players to toy with lmao.

Aaand don't forget the piano sound "Easter egg". Nah that's just a neat gameplay addition. Speaking about secrets: Anyone ever noticed the green book laying on the ground upstairs at the Armor-side of the house? The player is able to read it, and I tried so today, but zombies continued to backstab me and so I could only read small parts. It's in German, saying some things about "Germany's future" and "be prepared". I tried to read more but I died :(. Perhaps it's nothing but if anyone ever feels like to check out....appreciated.

Wonderful thread! I do have a question though-- do you think Groesten Haus has any larger secrets in it? It could be similar to The Giant, just as a bonus, but I really don't want to say that's all there is.
