I have just uploaded the latest release of Icar version 4. There are loads of updates, mostly in the equipment index section of the rules, which has been moved over from the old equipment index.

Personally, this release is an important one. Moving and re-rendering all the weapons for the equipment index section of the core rules was a mountain of work. Even though I had a good workflow of load-render-cut-crop-save-stats, it still took forever to complete. When you have a wall of work to climb up, it takes more than a normal amount of effort to get up it! I would find that sitting down in the evenings to work on it was more than I could handle and would end up settling for playing some games. During the meanwhile, Icar isn't being written and the hump is still there.
