I'm just going to say it, Unless they deliver at least 1 map per month and I don't mean a slice of map for Horde mode then it will have the same fate as Hunting Grounds.
Where are we, a year and a half after Predator Hunting Grounds release? I actually think it will be worse for Aliens Fireteam in its current state because there is no sense of Randomness and no PvP.
In Predator, unless you Private Match, you're not going to know what map you're playing in, what random mission is in that map, what Predator you're playing against, what weapons and perks that Predator has equipped and what is their playstyle. In Aliens Fireteam, as it stands right now, you know everything you will face everytime you play. The map. The mission. The enemies. How & when they'll attack. So that needs to change ASAP or a year and a half it will be a ghost town. Fingers crossed they do!
On the topic of weapon leveling, I wish weapons leveled based on actual usage, rather than just a set amount for taking them along on a mission and completing the mission. Like, if I take a shotgun and a pulse rifle but I never fire the shotgun, I shouldn't get equal XP for both guns. That would incentivize me to actually *use* the guns I buy, rather than just buy them and leave them in an open slot so they passively level-up while I keep using the guns I'm "familiar" with.
Yeah, this is my preferred method of leveling too. It's really a great motivator to use weapons you might not tend to normally use, and sometimes, you turn out liking them!
