I think we should discuss how much looking around corners will give you an advantage;
Humans - Will be able to see their defeat before it happens. Will be able to charge a luci early. However, if you have a luci you should have a helmit. No help.
Aliens - They have a radar, looking around a corner to see what's coming is not beneficial since they can pop out their head to check and easily get to safety due to their high mobility.
