@Klear:
Some of the previous beta versions were really hard, due to the smell and really annoying point blank spawn.
@Kornel:
Apparently, it is hard to keep high amount of ammo sometimes (especially with low marks in weapons). You lowered the amount of bugs, but the higher amount of crates (instead of items lying straight on the floor) causes ammo to appear in a random way.
Also, it is no longer possible to open a door, examine the room for ammo, and close it. This strategy no longer works.
Every room with Hunter inside is basically an opened room, and the opened room means you have all of bugs going after you. There are of course rooms with Security and Military locks, which can keep bug swarm, but you can't peek inside those anyway. Too bad bugs are so witty and do not destroy locked doors.
The key to early game now is to get weapons that use the most popular ammo in the game. The standard FN SCAR works well with 5.56. My favorite for 9mm is semi-rare SMG. And there is Combat Shotgun, that shines almost everywhere.
All in all, it is balanced so far, imo :P .
