1. The recently recently released screenshot shows a combat in rainy night appearance. Will night or different weather be limited to campaign mode? And will it be possible to select it on the map editor?

Night and rain effects will be possible in campaign mode but are not likely occur in multiplayer. Additionally, these effects will be available to map editors to use for custom maps.

2. Does blizzard plan any interface options for people with physical issues (such as color blindness, deafness)?

This is a good suggestion and we would like to give all players opportunities to enjoy our games. While we may not be able to create accommodations for everyone, there have definitely been strides made to accommodate more players than the previous StarCraft. For example, you can find more alerts on the screen, such as attack, build complete, and more in StarCraft II and this system will be helpful for players who have difficulty hearing the game sound.

3. Will there be any multi monitor support?

StarCraft II will support widescreen but not multi-monitor. Widescreen is definitely becoming more of an industry standard, but multi-monitor support for StarCraft II may be too great of a tactical advantage over other players without more than one monitor.

4. SC1 "caster" units did not have a regular attack; some of WC3 "caster" units did have a regular attack; will SC2 "caster" units remain attack-less?

Some of the caster units in StarCraft II like the High Templar and Infestor lack a default attack, but there still are some caster units which also have a normal attack ability such as the Mothership and the Ghost.

5. When two opposing forces come to a Xel'naga tower who gets control? Is it the person with the largest army or is it on a first-come/first-serve basis?

When two opposing forces are near a Xel’Naga Watch Tower, they both lose control of the Watch Tower, regardless of the size of the army or the order of who arrives first. For example, when you have a ground unit next to the Xel’Naga Watch Tower, you will get vision of the area surrounding the Xel’Naga Watch Tower. When the opponent’s unit approaches close enough to control the Watch Tower, the Xel’Naga Watch Tower will shut down and both you and your opponent will lose the increased visual range given by the tower.

6. Is the charge ability only limited to the distance between the zealot and its target or is it also limited to the time that is needed to reach the target? Presumed you have a zealot on a cliff and you want him to charge an enemy unit below the cliff, will it charge all the way over the ramp or will it stop charging after some time?

Zealot’s Charge ability is based on the ground range, regardless of the height. So a Zealot on the cliff will not start charging a unit below the cliff, even if they look like they are visually right next to each other. The Zealot must be within a set pathing distance from the target for it to activate it’s charge ability, meaning the path in which the Zealot takes to get to the target is a set amount. Additionally, Zealots will not be able to charge through cliffs. They must go around.

7. Are you going to add some of the best custom maps to the regular ladder pool?

In the future, there will be opportunities for map makers to get their maps added to ladder pools. These maps will of course, be selected based on quality, in terms of competitiveness for multiplayer games.
