Finally making it more than a year without any major catastrophes, have a few questions about the play style I've adapted into
1) Are there any early to mid game lethal melee weapons with better returns than a Spear for no armor to medium armored enemies? At 16 turn units, with armor penetration and high enough Acc that even my least trained melee gals never miss, I'm really having trouble seeing why I should pick up any of the heavier, deadlier weapons due to their energy cost and the fact that the spear has yet to fail me. What kind of weapons should I be looking to upgrade to, and what enemies would even make me want to?
2) What kind of weapons have ammo available in the black market, and are there other ways of unlocking ammo for purchase other than researching the weapons? For example, I got a sniper rifle early, have researched it, and did not unlock the ability to purchase it like you do with some other guns (IE UAC carbine). What techs do I need to look out for in order to unlock this type of ammo for purchase, or is it craftable only/loot only?
3) I figure that I should wait until I can actually field real interceptors/spy zeppelins before I start expanding, am I right here? I have overcharged radars, a cool 10 mil lying around, but don't want to tank my economy expanding too early. Additionally, once I start fielding interceptors from other bases, will it make sense to station my gals there for protection from retaliation? Base defense seems like it will be a huge blindspot if I start setting up unmanned outposts or interceptor stations without a reasonable force for base defense, am I worrying over nothing or is there any significant threat to bases without tons of gals and attack dogs?
