Video headaches

I had really an awful time trying to put together a decent trailer video for the demo that I just released.

Apart from all the trouble I had trying to figure out how to use various video editing tools, the quality of the uploaded video on youtube seemed very bad compared to what it should be, so I did some screen captures and compared the result side by side.


What I found is that youtube used SD (i.e. low quality) by default, which is very bad. You have to specifically select HD from the embedded youtube video to play HD quality, which few people actually do. But even youtube HD is pretty poor quality. You notice in the image above the colours look washed out. The soldier in the middle looks like he is in black and white. Vimeo has better quality as you can see, unfortunatly vimeo can't be played in full screen mode in these blogs. Still, I'll take it. After spending so much work getting the graphics just right, the last thing I want is youtube crappifying my game trailer.

Hello All,

Today I have prepared a special version of Merc Tactics for game play testing. You can download the installation program here: http://astronautz.com/MercTactics/MercTacticsSetup0.5.exe

Recapping, Merc tactics is a turn-based squad tactical combat game, similar to games such as Jagged Alliance, Silent Storm and X-Com. Below is a sample video of the game:


I am inviting people on GameDev to try out the game and give me your feedback. Specifically, I'd like to know if you found the game too hard to play, too easy, or too tedious, or if you have any ideas of things that are missing to improve the game play. You can have some fun playing the game and also participate in the development process!

The game has two modes: Quick Battle and Campaign. For this test I am only testing Quick Battle.

When you launch the game, you will see the main menu, as shown below:


Choose the desired battle and select "Launch" to start the battle. You probably want to select one of the easier ones, until you get the hang of it. Also, selecting "Extra Enemy" will mean there is a three way battle with two enemy militia groups, all fighting each other. Selecting "Allies" will include a friendly militia fighting on your side.

Online help is available here: http://astronautz.com/MercTactics/help.html.


This game requires OpenGL version 2.1 or higher, so it should work on most PCs.


  • This game is more focused on making use of available cover, and close-in fighting, rather than long range sniping. Each scene requires a different approach, depending on how it's laid out, and as all scenes are generated procedurally, that means there is a huge variety of battles.

  • Although this game is inspired by Jagged Alliance it, it does not try to copy it. Notably, I designed the game rules and mechanics with simplicity in mind, so as to be easy to play on tablets and smart phones. My design criterion was to only include features which made the game genuinely fun to play and eliminate features that just add complexity for complexity's sake. That being said, there still is a lot of features that are missing, because I simply did not have the resources to include them in "version 1.0". You can look at "version 1.0" as just the beginning. Version 2 and 3 will add the missing features and greatly expand on this game.
  • This is a beta version, and you may notice some rough edges. Particularly, the user interface and some of the graphics have yet to be finished. Do not worry about these things, because right now I am only testing the game play.
  • In this demo you can in fact play Campaign mode, if you want to. Although it's not finished yet and there is no help documentation for that. :o


    I had to change the video, because of youtube quality problems.

All scene's in MercTactics are generated randomly.
Previously, I've just "sprinkled" stuff into a scene randomly, but this doesn't look very good. Stuff tends to be clumped together in the natural world.
So, I used a Perlin noise map to control the placement of plants and rocks.
In fact, for the rocks I use two perlin maps, one to control size and one to control colour, because rocks of the same colour tend to be clumped together as well.
I use a less detailed perlin map for tone, so the colour changes more gradually.

Finally, I use a third Perlin map to control the placement of grass, weed and trees.
This is how the complete scene turned out:

During the last few weeks I was working on the terrain for my game. All scenes in the game are generated randomly, so the ground texture needs to be randomly generated as well.
I do this by building up several layers. First, an opaque tilable texture is repeated to establish the base. Then on top of that transparent decals are laid down with random location, rotation, scale etc. Then, track marks, road tiles, pavement / cobblestone and grass decals. Below you can see the results.



I think it turned out pretty well.
Unfortunately, the scene generator needs more work - some objects are placed a bit oddly.

Some new artwork

I had to put the game on hold for the last 6 months, because I've been too busy working, but now I'm back on the game full time.
Last week I started on the 2D artwork. These are some dialogs for the game's story line.

New beta version

I released a new version of Merc Tactics.
It can be found here: http://astronautz.com/MercTactics/MercTacticsSetup.exe
Instructions on how to play here: http://astronautz.com/MercTactics/help.html
The game should now work on practically any GPU. I relaxed the OpenGL requirement to 2.1 and tested that it works even on an ancient GeForce 7600 GS.
Also, there are a lot of bux fixes, tweeks, improvements and some new features.

As promised in my last post, I am releasing an early beta version of Merc Tactics.
Merc tactics is a squad based game similiar to Jagged Alliance. It is set in a lawless country plagued by tribal warfare. You control a ragtag band of mercenaries, which strive to rid the country of the gangs and restore order.

You can download the game here: http://astronautz.com/MercTactics/MercTacticsSetup.exe (Windows version)
Instructions on how to play here: http://astronautz.com/MercTactics/help.html
A short video of the game play is here:

In my opinion this game *rocks*, however I'd like to see what other people think of it. I'm especially interested in feedback about the game play - Is it too hard? Is it boring? Anything you think is missing and ideas how to improve it are most welcome.
Bear in mind, though this is a very early beta - many features haven't been finished yet and there is a lot of placeholder artwork ohmy.png .
Although it is inspired by Jagged Alliance, it differs radically in many ways. The UI and game play is much more simplified, to make it playable on a tablet (which is the target device).
Also, battles are not limited to two parties. You can enter a battle that is already on-going and new parties can join in on a battle at any moment.
Everything in the game is randomised. The strategic map is randomly generated by an algorithm, as are all battlefield scenes. So, no two battles will be the same and no two games will be the same.

Update 26/9/2015:
I uploaded a new bug fixed version of the demo. Download from the same link above.

I am starting this blog by posting a video preview of my new game, Merc Tactics. I hope you like it:
Merc Tactics is a squad-based game, inspired by the likes of Jagged Alliance and Silent Storm.
The game is set in a rural a district plagued by tribal war. You control a ragtag band of mercenaries, which strive to rid the country of the gangs and restore order.
I want to get feedback on the game play and to that end I am working on a PC demo.
So, watch this space - as soon as the demo is finished I will publish it here.
