Just to share some tips that some of you might already know about listening to sounds that can help pinpoint your enemy's location
1) Footsteps -- > im sure all of you guys know about this... every FPS gamer should
2) Power jump/jump/ledgegrab sounds --> I think crysis 2 players should be familiar at recognizing these sounds as well
3) Stealth/Armor mode transition --> yes, you can hear if your enemy transitions into cloak/armor mode nearby... it sounds like a soft high pitched glimmering sound.... make no mistake... if you hear it nearby and ur radar shows no friendlies nearby....expect a cloaked/armored enemy in the vicinity
4) Proxy Alarm verbal reports --> if an enemy uses Proxy Alarm, you can actually hear them verbally reporting if an enemy is nearby them. Its not a loud shout but they will say things like 'someone's close by', or 'they're definitely around here somewhere'. I found this useful as a defender in assault, cos I heard this verbal report and instantly i know that an enemy using Proxy Alarm is nearby.
Alternatively, if ur gonna surprise ur enemy and go stealth mode... do not load this module. You might not hear your ownself shouting the reports, but the enemies definitely can.
5) Radar Jammer verbal reports --> enemies affected by your jammer will also have a verbal report that you can hear... like 'they're jamming my radar' or something
6) other verbal reports --> there's some other verbal reports like 'They definitely know i'm here!' although im not sure when these are triggered...maybe being tagged with Visor or Visor Enhance? or Maximum Radar?
7) Rustling sounds from a camper --> If you're camping, and u move around ur mouse, you're making rustling sounds that can be heard by the enemy. Just keep your mouse perfectly still, if you really want to hide. If you're hunting a camper, keep your ears open.
8) Weapon sounds --> i think most of you know these already... you can hear reload sounds, and weapon fire... etc
9) Other noises --> things like enemy accidentaly kicking a crate, or brushing past a tree.... or random noises that wasn't there before.... don't dismiss it instantly as ambience.... you might be wrong...
