New update was just added to the game. I've added a support of different levels of terrain in the game, with the additions to couple of new rooms for the generator. This will vary the tactics a little, your soldiers and enemies will receive a 10% accuracy bonus for each elevation level, if they are higher than their targets, and 10% penalty if they are lower. You can also use edges of elevated terrain as a cover.
Right now this is a relatively small update, but it will allow me to create more varied levels in the future updates.
New update 0.20 - elevated levels
