Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We use Steam Early Access to get feedback from the community and give MarZ: Tactical Base Defense its final touches.
MarZ is developed by a team of two. Since December 2014, we have been working on creating challenging gameplay, developing new game mechanics, producing high-quality graphics and writing a thrilling campaign. MarZ has now reached a level of development where it can grow and evolve from all the great feedback we get. We want to know if you like the game and to hear all your ideas, criticism and wishes.”

Approximately how long will this game be in Early Access?

“We plan to release a thrilling and challenging tactical base defense game on April the 4th.”

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

“We're using the Early Access period to update the game with loads of new content, bug fixes and stability improvements. The full version will include a 20 mission campaign, a skirmish mode and a level editor.”

What is the current state of the Early Access version?

“In terms of major content, we're getting very close to the full package now. Since the Early Access Release, we have expanded the single-player campaign from 13 to 20 missions. The story campaign is thus completed and can already be played through. In addition, depending on the progress 2 alternative endings can be unlocked.
With the last update, the long-awaited skirmish mode is now available. We've developed this new mode based on feedback from the community.”

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

“The early access price has already been increased from 14.99$ to 21.99$. This reflects the extra time and content we have put into the game since Early Access. Due to the price rules of Steam we had to change the price before release, to be able to welcome new players with a discount at launch.”

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

“Early Access gives us the chance to involve a large group of players in the development of MarZ. Your feedback helps us to understand what works and what can be improved. With F1 you can send us in-game bug reports via our bug report system.
To gather and discuss your feedback, we use the Steam Community Forum. At the same time, we post our news via our social media channels:

MarZ - Demo Update

Hi all,

Launch day is getting close. Only 2 weeks left until MarZ: Tactical Base Defense will leave Early Access! As you can imagine we are getting more and more excited every day. We are working as much as possible on the last details to make a smashing 1.0!
So here’s one last short and crisp news drop before the big day.

We have just updated the free demo. The demo still includes the first 3 missions of the story campaign, but now contains new values and balancing that will feature at launch. So it’s a kind of a pre-access version to 1.0. We worked really hard on balancing and are pretty happy with the result. Of course, the new balancing has an even stronger effect on the later missions, where the whole range of towers is available to you, but even in the early missions you can feel the difference.

We’ve prepared a fancy new gameplay video, which will give those who have not yet played MarZ a good idea of what the game is all about! Of course you can also try the free demo to see if MarZ is something for you.
For launch day we plan to collaborate with some great youtubers & twitchers who will be live streaming MarZ on our Steam store page. We’re really looking forward to watch them playing. So even if you already own the game, the page is worth a visit on April 4.

Last but not least, to celebrate the launch and welcome new players we will offer a launch discount of 10% – YAY! :steamhappy:
So tip of the day (if you don’t own the game already – tell all your friends if you do!):
and buy on April 4.

We will now dive back into work as there’s still plenty of things to do before launch day. Stay tuned, any support is very much appreciated! If you want to stay updated about further development of the game you can also follow us on our social media channels:
