First my suspicions about the timer for the collectives drop ship reinforcements is correct, on v1.10 the I hear the alert about incoming enemy reinforcements at 56:45, and the timer for the level is 60 minutes so that makes the first drop ship arrival at about 4 minutes 30 seconds, and the drop ships then continue on the same interval appearing roughly every 4 minutes 30 seconds until you close the drop zone.
Fixed. Appears at 4 minutes and requeues itself every 4 minutes after that for Normal difficulty.
Second about the VTOLs on v1.10 there are 5 leopard VTOLs, equipped with the cluster bomb bay, and they only seem to target the command centre, unless they actually succeed in destroying it, also there seems to be 2 ways to deal with there VTOLs the first is to shoot them down because there are only a limited number and they don’t rebuild them, the second is to knock out there command centre, which stops them from summoning there VTOLs to attack you, the interval of the VTOL attacks seems to be around 2 minutes to 2 minutes 30 seconds, I'm not sure what the exact interval is I'd need to look more closely but it should be around that, also there are no lancer VTOLs on Beta 01 so this is also incorrect.
Fixed. The first VTOL wave comes at 3 minutes and repeats every 3 minutes after on Normal difficulty. No lancers.
The VTOL targeting focused exclusively on base structures above all else (CC, factory, power gen). As you can imagine, that was quite silly (often leading to them being pure AA fodder) and makes more sense for them to attack the thing closest to them.
As you can see there are no upgrades for the lancers so that is another thing that is incorrect on Beta 01 on master.
I know that for sure that the Rocket Autoloader upgrade comes from first base on Beta 03, because I just checked it, as for the Lancer HESH Rockets and the Lancer Laser Designator upgrades, I'm not sure where you get those on v1.10 or if you are even supposed to get those at all they may well of been added from skirmish mode, I'd need to play further on to know for sure.
Messed up the research order did I? I'll let you test further before making research changes.
Buildbot is down so a mod will have to suffice for now.
Right now the HESH rocket upgrades depends on having bunker buster, HEAP mini rockets mk1, and the rocket autoloader. From there the rest of HESH and rocket autoloader upgrades are linked together. We could delay the HESH upgrades until Tank Killer is research.
