I saw a global for a found container in that was from the BS, I noted that was mentioned in the notes, is there always a container to loot if you finish the sim ?
The other questions How many mobs are there to be killed ? Looked like 25-30 to me.
BTW it is a fun mission but a bit fast and furious for me :). Reminds me of old team fortress etc.
At the end of each battle simulator there is a chest with a minimum of 3 ped in loot. Only if you get the message at the start that the reward has been increased you will be able to get more from the loot chest.
There might be about 30-40 mobs, maybe even 50, and that is not counting the turrets. There are many turrets you need to take down too.
