Even do the Space Age: Mars! did not come out jet, I'm concerned about one of the new GBs introduced in this era. The GB in question being: The Virgo Project This Great Building has the ability "Missile Launch", which gives you the chance to kill half of all enemy units at the start of a battle. Additionally, the building also produces coins for your city. Since we did not jet see this building in action, I can not properly assume how the levels of chance this building will have. That being said, we can compare it to The Kraken The Kraken is a Great Building that comes with a skill: First Strike. At the start of the next several fights, there is a chance a unit from the enemy's defense army will be killed immediately. This only applies to the first wave of a battle. On top of the First Strike skill, The Kraken will also produce Forge Points. The Virgo Project seem to be essentially a direct upgrade to The Kraken, seeing as how the ability "Missile Launch" allows you to delete 3 of opponent's 6 units,First Strike. while only deletes 1 of opponent's 6 units. The question I propose is: Do they stack? Or one completely negates the other? let me show you an example: Let's assume you made a stop at the end of Modern era, waiting for space age: mars! to get released so you can trade forge points for goods needed for The Virgo Project, before you mode to PME. Since you allready traded for The Kraken before and you now have it on Lv 80 (which gives you 98.08% chance to insta kill 1 unit 23 times) you'd now have bot of them, and you might even wait a bit before moving on so you get a decent level on The Virgo Project. Now with those preparations ready, you face against Che Guerrero in The Province of Rung Chien Dau against his 1 Armored Car 1 Sniper 1 Conscript 1 Tank 1 Mechanized Artillery the question I pose is - if there is a chance for both abilities to activate will that leave Che Guerrero with: only 2 units (both abilities stack) only 3 units (Missile Launch overwrites First Strike) only 4 units (First Strike overwrites Missile Launch) or is there a line in the code that only one can activate? Someone from staff please clear that for us please.
