Hi, my name is Peter Groot and I go by the alias MentalMars. In this corner of the website, you can learn more about me and what’s going on with the site.

I’m from Holland and natively I speak Dutch, therefore, English is my second language. During my “day” job I bake bread for several stores and in my spare time, I create awesome content for the games I’m passionate about.

Throughout the years, my main focus has been on Battleborn and Borderlands, which are both games by Gearbox Software. Because of my dedication and the quality content I put out, I have managed to build a good relationship with them and also their publisher 2K Games. This has resulted in exclusive content, interviews, and giveaways.

So if you are as passionate about these games as I am then please consider bookmarking this site.

Student of the Craft

Your journey is like a prototype for how well a relationship between developer, publisher, and their community should be.

You’re one of the most professional people I’ve had the chance to work with.

I think your best content creation days are still ahead of you! You’re a student of the craft and I think you’re going to go so far.

Awesome, Respectful, and Hardworking

MentalMars has been awesome since the first day he and I interacted online, and he’s always been respectful of both our time and jobs as well.

I’ve always been happy to leak as much as I can (and probably more than I should) to MentalMars because of his attitude and hard work.
