Yeah, they pretty much were just hating on it because, and for a fan of the series, that guy is wholly incompetent, but moving on…
I thought the explosions looked good for the series, but ¯\_(ツ)_/¯
The unlock system seems great to me because if you like a certain type of weapon, you can buy it as soon as an upgrade is available. And you won’t ever not get it because you outleveled the drop range. When my son and I were playing 5 this week, it took him 40 missions to replace his starting hand cannons for his fencer. That wouldn’t happen in Iron rain. EDF always had half this system (you couldn’t get certain weapons until you got to a certain mission/difficulty range) but you had no control over the drops. Now you do, in effect. You can also switch class roles at any time with no dropoff (and armor purchases apply to all of them).
I also really like the idea that nothing is restricted by class anymore. The 30 second timer to pick up gems is nice. Enemy variety is quite large in the first few missions, with the dung beetles being an especially cool addition that changes things up a bit (and fighting a rebel human faction opens up lots of possibilities). I like the cutscenes so far. They are suitably cheesy but haven’t overstayed their welcome, at least early.
One thing I’m not sold on is the overdrive system, but we will see.
I’m having a blast with air raider in edf5, and air raider isn’t a thing in Iron rain, but that’s a good thing in a way because I can play it in a totally different way.
