What the developers have to say:

Why Early Access?

“CYPEST Underground is already a good game, but we are at a point now were we need to get more feedback to make it better. The game mechanics look easy, but testing and new missions are a lot of work. Through Early Access we hope to make the right decisions to make CYPEST Underground really great.”

Approximately how long will this game be in Early Access?

“Until April 2019.”

How is the full version planned to differ from the Early Access version?

“The final version will contain more missions, features and content. The local two player mode will be further improved.”

What is the current state of the Early Access version?

“Three missions with 32 levels are fully playable. The highscore lists and medals are working, the two player mode is only rudimentary working. You can already get a few hours of fun.”

Will the game be priced differently during and after Early Access?

“We don't plan to change the price.”

How are you planning on involving the Community in your development process?

“We did already listen to the feedback of the users during the development of the freeware version. We're reachable via Steam, Facebook, Twitter and the CYPEST web page. We will discuss feedback internally and develop it when the outcome is positive.”

About This Game

As a computer virus you are infiltrating various servers and avoid their defense systems to reach the CPU. This is like a racing competition. Every progress gets you points. Your best score for each level will be saved in an online highscore list.
The highscore list is separated into 7 continents, 26 regions and 216 countries. You can see your ranking everytime for the respective location. Set your own goals! Do you want to be the best at your favorite level in your country, continent or even worldwide?

Besides the highscores for every level CYPEST also has a "Hacker-Olymp"! There all scores of a player are summed up for universal global highscore list. The game mechanices are child's play. The virus is flying upwards automatically, you'll only need to press left or right on the keyboard or gamepad. Easy to learn, hard to master. You can play the game with your friend on one PC. In each level you can also get up to four medals for your score.

About the development

Our goal is to develop an aracde game which brings back the feeling of the 80s and 90s without copying another classig game one to one. You'll learn the game mechanics in seconds and have fun immediately. On the other side you can play for many hours to master the gameplay.

CYPEST was originally developed as a freeware game and can still be played on the website of the game for free. It is running inside the browser and on Windows. The twenty freeware levels are 100% free.

CYPEST Underground is the further development. There is one new mission with 12 levels. The levels from the freeware were overhauled. The game is now more beginner friendly, but experienced players will also get a challenge. The medal system is completely new. You can play the freeware and see if you like the gameplay. It is like an extensive demo.

You can not only see your accomplishements inside the game, but also on the CYPEST web page. You can also share them on every social network without hassle.

CYPEST Underground is 100% integrated into the Steam ecosystem. You don't have to register a new account. There will be achievements and many other things. During the first start of the game you'll need to set your location and can play immediately. Highscores from the freeware can not be carried over. The game is running on a custom engine written in C++ and based on SDL2. There was also a custom level editor used, which will not ship with the game. Besides a few alpha and beta testers, CYPEST was developed by two people.

Privacy protection

We're only saving the data which is absolutely necessary, regardless of the freeware or Steam version. The game is only connecting to the server if one logs in or reaches a new highscore. The score will be saved into a database. We don't save how often you play. We will not know how many times you tried a level. There is no tracking code. Only the data is saved which is needed for your maximum gaming experience. The statistics you'll see inside the game will only be saved on your local machine.
