The demo has been updated :
Towers can now have a different vision and fire range. This will allow very long range support weapons that require other towers to provide vision.
Missile turrets now have more fire range than vision range. This requires players to provide the vision with other towers.
The missile tower firepower is not changed. So it might be too weak now. Will probably increase the range and damage with future updates.
The mortar tower/building will not be included in the demo. It will feature an inaccurate long range projectile. It will have almost no vision range.
Enemy units will slowly become visible when entering vision range. Instead of popping into existence, the part of the enemy unit will only be visible, where the player has vision.
Enemy missiles do friendly fire damage. So its possible to throw enemy missiles at the enemy to do damage to them.
Difficulty of the 2nd and 3rd mission are reduced. In the second mission there are less tanks to discover and destroy. In the third mission there are less enemies produced and the first attack is delayed.
Reduced level loading time. Some of the loading is spread out over time to reduce the loading time during the first few frames of a new mission. On older hardware (below minimum spec) I hope this reduces the amount of hang crashes.
