I played before 2009 there is a casted game on seton with me. I learned about factory attack move maybe now 1 year ago. The most useful things should really be mentioned somewhere more obvious. As well as some tactics like air fight and so on. Or maybe i do not know the point where i can find all this stuff?
Factory attack move (alt + right click) t1 bombers automatically attack targets in the way and engis go to the attack point and start reclaim with very high range
For airfight needed button (s for stop) planes are searching new targets in front of them dont click to often or they ll stop does not work good with t1 planes essential for asf and t2 bombers
Assisting already assisting engis for factories - if you sent all engis to a factory assisting and the first engi starts to built you can select all of them again inclusive the one who already started and assist with right click the engi which is already building. Effect is all engis in built range stop immidiately at their position and assist. They dont drive to their normal assist positions anymore.
In general Engi use if enemy tanks or reclaim or whatever is in building range and you cant to reclaim it press ( S for stop + E for reclaim) otherwise they will drive to close lose time and not stop at maximum range. Essential for acu reclaim on any map like seton or whatever.
Same for assisting buildings press (S Stop + R Repair)
T2 bombers also should be mentioned in a guide because they are difficult to handle. If you use Patrol they will never ever attack ground units only air. You need to stop them then they kill air with priority and if there are no air targets anymore they attack ground. Attackmove exactly the same. They go to the end of the factory attackmove waypoint and fight only air on the way there. At the moment they arrive and lose all orders if there are no air targets anymore they attack ground.
lots of thing should be mentioned here more. Spread attack i didnt know as well
