Thank you. I redeemed the Code.

I have decided to make it a bit challenging this time.
The game is Monster Prom 2: Monster Camp (GOG code)

The code is:

0@@!$C
$$&!8E
K%5Z$D

The order of the groups is based on the end of each group, DELTA CHARLIE ECHO.

$ - The number of matriarchs in the beginning.
# - The Father The Son and The Holy Ghost
$ X # = &!
! + $ = %
% - & + $ = @

Good Luck

Update: The code has been redeemed. Have an exceptionally-soothing end of the week.

Doom 3 (includes original version, Resurrection of Evil expansion, and the remastered BFG version):

Thanks very much, Palestine!

Nice riddle. But the code already seems to be used as I get the message "This code is currently being redeemed by someone.".

A polite reminder (since you still seem to be online): 30 minutes ago, I had sent a private message to you regarding that game.

Sadly the Ninja who got it didn't send a thank you.
I sent you a private message.

There was a time I was stealing video games : (
https://www.gog.com/forum/general/returning_childhood_theft/post29
Since about 2004 I have been getting it legally to myself and others.! : )
And from about 2012 Jog.Kum (GOG) became my only source of legal games, leaving all other DRMed services behind.
Offline Installers were the sole argument that convinced me.

I am here burning with Kundalini ; ) that energy does not accept DRM nor marketing tricks or weak spying tactics, neither personal nor industrial. It's open to everyone having a true heart.

and...

There is a wonderful little game that can be played a few times in a row... if you like camels, haggling, and water.

The Caravan

The code is written the same way as Arabic and Hebrew...

20 years ago I learned that
إله إبراهيم وإسحاق ويعقوب
זהו האל היחיד
and someone on this forum said to me that is Thy God of Brian too
Yes!, And of Brian too! ^

I did that too, my friend, in the past. :(
It's as they say: When you're young and have time available (to play games), you don't have enough money (to buy them). And when you're older and have enough money, you don't have enough time...

Thank you!

As a 12-year-old boy, I went under the Train Station to find something amazing...

You might think everything but it was a Video Games Saloon made in a tunnel underneath Wrocław's Main Station, and like... 15 different arcade machines... There was a Spider uncovering pictures, a Tekken 2, some F1, some arcade shooters, some other stuff...
...and there was Metal Slug... I was playing it for two years like a once a week multisessions... dropping in złoty after złoty coins...

This is a game about being a soldier shooting other soldiers and machines.... but it was a game... not a real shooting... I did a lot of real shooting... to the shooting target on a shooting range... I met Renata Mauer once, she had a nice smile for everyone... I learned that you can't drink alcohol as judges are counting it as a dope for shooters... I made 10*10 being sober... They checked the target many times but it was real...

That's my adventure with guns, and video games never gave me any wrong ideas of hurting other people.
Because Video Games are for taking stress off you! : )

This is the code
212B1-7letterBDcipher-FEcipherletterC-1DB2B
I shot off one cipher and one letter, from a great distance : )

Cute! But someone else will enjoy it more than I.

Thanks for the game Seb3.7. :)

: )
Congratulations! Thanks for solving it. Please Enjoy! ^
One more is coming today in about an hour ; )
Thinking about it, there were 10*26=260 combinations. Congratulations! Please enjoy! ^
