I'm currently working on a new menu page. On this page you can define the ratios of content you can find in crates. The menu itself works, but the values are not in use yet. Should take me but a moment to put them in use though.
Screenshot on the side show the new menu window, as well as the ratios that have been in place in recent version.
Weather & Wind
Also, optional weather conditions 'Rain' and 'Thunderstorm', as well as 'Wind' will be available in the next version:
* Rain pushes units and ballistic projectiles down ever so slightly to make a minor difference. (Rain is not available on Lava-themed maps.)
* Thunderstorms may happen when Rain has set in, and they're scary. All trees and vehicles in the upper half of the map are at risk of being struck by lightning between turns, which deals a lot of damage, enough to kill units such as gunships and gyro scouts in one strike. The higher the altitude of a unit, the bigger the risk. To be struck by lightning requires a direct route from the unit or tree to the sky, so keeping units under land tiles and next to tall walls can reduce or even remove the risk. Just don't keep your Gunships at the top edge. You're looking at a whopping 20% chance to be hit there... Every 50 pixels down is 1% less risk. (Thunderstorms are not available on Lava-themed maps.)
* Wind affects mostly projectiles' speed and trajectory, but can also affect unit flight slightly. Wind changes slightly between turns. Unlike most other artillery type games though, the wind doesn't take drastic turns like being strong to east one turn and then strong to west on another. For that to happen it takes several turns in Tank Game, and a lot of bad (or good, depending on situation) luck. 'Major Ballistics' are affected most by wind, 'Minor Ballistics' not quite so much, but still somewhat. Wind strength is measured on scale of 1-30.
Second screenshot on the side shows a tree struck by lightning, as well as wind and weather icons. Wind is at its strongest, at 30. Rain tilts to the direction of the wind, and trees bend slightly in the same direction as well, and generally sway faster in wind. At 0 wind, the trees are pretty much static.
'Weather Conditions' and 'Wind' are separate options in the main menu, so you can have both, either or neither.
