What's your problem guys...
I could say the same thing 'as usual' and will do it here now of course cause some of you can only complain it seems...
Do it yourself, if you have the time and skill to do it the way you think it should be done, period.
The BonusPack is using a mix of sounds used in 2.9 and sounds we originally recorded years ago for these weapons. With only a few of the team being able to provide some of their free time during the months since the 2.9 release, we simply had noone to record new sounds for us. In addition, INF is not Hollywood, but I guess you all know that there is a difference between real sounds and 'real' Hollywood sounds...
The AT4... added as a 'base' for anyone who wants to use an EAS objective that features a weapon and a target that needs to be destroyed (EAS actors for this are included in the BonusPack). It uses the very old mesh and skin of the old 'original' from our Unreal days. It is a one shot weapon in INF, so 'whoring' shouldn't be an issue. So we added it to the standard loadout stuff instead of leaving it only for the mappers to toy around with.
In addition... some of you take games and mods way too serious sometimes it seems...
