Ya, I just finally had a base defense mission today. I've had great success with batteries, with even the paltry 2 at my main base destroying like 4 ships over the months that I let get to the base because I wanted to finally try a base defense! Finally a transport made it through. I was however very disappointed on a many levels with the base defense mission.
1. The defense batteries did NOT reduce the alien numbers in the carrier at all, even though the 1 hit from a plasma battery reduced the ship to 41%. I ended up with 19 aliens killed which seemed suspicious since the most aliens I'd encountered up till then was 24 I think, in the base with the commander. Didn't seem like there could have been much reduction for 60% health loss of ship. I reloaded and did it over till the batteries scored 0 hits at all. Same 19 aliens at 100% ship health as at 41%.
2. What is up with the soldier equipping right before base defense? I had my Shrike crew in base, and assumed they at least would be the defenders, right? Wrongo. Of the 10 shrike team and 16 other team members in the base, I didn't get to choose who fought. Apparently the computer picks what, top 16 highest ranking team members? You need to TELL people that during the mission briefing. Luckily I wasn't on ironman or I would've lose half my senior team members. That first time over half the people that showed up didn't even have armor because I thought only the shrike crew was going to fight, and apparently about 4 of them were too low-ranked or somehow didn't get selected. Most had M16s, and 3 had shields and no guns! I would have lost if the 3 alien entry points didn't happen to randomly spawn in the same 3 adjacent rooms in one corner, which allowed my heavy plasma predator gunner to mop up decently. Why on earth do you not give the player a hint as to what's about to happen? "Your top 16 ranked xenonauts [or however it chooses] will fight this battle and you don't get to choose, equip appropriately". Is that so hard? To let the player know which soldiers are going to get to fight? Because it's not obvious.
3. Wouldn't it be logical for the player to get cameras on the base, like after the first 20 turns of a terror mission? I realize you don't want to make it too easy, but it's pretty illogical that somehow I have eyes everywhere in peoples houses and offices after 20 turns, but not in my own friggin base? At least give some flavor text "the aliens have haxed your cameras, you'll have to do it the old-fashioned way!"
4. Despite all these things that *should* have been mentioned and weren't, one thing that *was* mentioned - too much damage to the base will result in structures being unusable - doesn't even happen near as I can tell. One of my quantum labs got absolutely mauled, but I couldn't see any difference. Does like, every single piece of scenery have to be reduced to rubble? To judge from other posts I've seen this is a well known non-event. But it was disappointing and you may as well remove the warning text if it's not true.
5. I can't close my own doors in my own base? Really? REALLY? At this rate I'd rather fight the aliens in their own ships and bases.
I can deal with most of that, but the soldier selection thing is unforgiveable. It makes no sense and flies in the face of everything the player has encountered up to that point. I'm still not sure if it selects them by rank order, or some other weird priority. Is this really how base defense is going to remain?
