1. will I still be able to obtain 4 hovers in FE map using the FE Story questline alone? What should I do from now to make sure that I wont mess that up? (ie, moving towards the PE, PME...map until I get to FE map).
2. I understand that the bonus questline took over a RQ slot until whenever, is the bonus questline matter at all in obtaining HAU?? or it just prevent me from having 2 RQs? if thats the case, I can be ok with it until I got 4 hovers.
3. based on the reddit guide, I am NOT in Industrial Age yet, my Story questline is NOT at Truth or Date yet, my cMap is NOT at FE yet.
Can I still advance the Story questline (might require research tec) and stop when Truth or Date appears from now (CA)? and can I keep clearing sectors in continent map however possible and stop at FE map to follow instruction from FE map when I reached Truth or Dare? OR - I should follow the guide on every steps from the PE map/quest to get the other higher age units while advancing the cMap?
1 Yes you will still be able, if you are careful. You can get four hovers in Industrial with no saved techs in Colonial (just) and you'll have one or two extra.
2 You are stuck on the bonus line only until you reach Modern Roads, which if you are careful about tech will come when you do the Long Lived Man quest in the Modern Era storyline, well before you get the hovers.
3 You should STOP clearing the continent map however possible. Charging ahead has already caused you grief and will cause you more grief. Catch up the story line, and don't attack further into PE. Actually, taking the first sector (Havre) is okay, but no more.
There are several good reasons not to blindly clear the map ahead, apart from missing out on intermediate higher-aged units. Going for the hovers takes careful progression and the last stat I read suggested most people who try it fail the first time.
I agree with King, you should research the field guns to move forward in the story line. When you get to the quest "Set Foot", take Havre. Scout when you are told by the quest but don't attack/take any sector beyond Havre just yet. Acquire four sectors in the quests Let the Wars Begin and Peacebringer by negotiation, NOT fighting. You will be able to continue the quest 08/15 through researching one of your remaining two. However, if you plan to go to Industrial immediately, I recommend you don't do that, but wait until you move up to Industrial to move forward. That way you'll save an extra research for Arctic Future if you want it or for a Tomorrow Era jump. You shouldn't be attacking sectors at this point in the questline. If you will be staying in Colonial for a long time it is worth pushing past 08/15 to get the tanks or conscripts using one of your two saved up researches.
Either way, once you have your choice of the tanks or conscripts (both are superior to the snipers in my opinion) it's fine to clear the Progressive map, but I wouldn't go much further into the ME map until the storyline catches up.
Hovers are probably better in PE. Turturrets are probably better in Industrial, but you can't reach those until PE anyway from where you are.
