FAST UPGRADE OF WEAPONS AND ATTACHMENTS

In this guide I will tell you how to quickly upgrade weapons and attachments to them, without much effort, in just 15-20 minutes.

Short

You just select "demolition: single/cooperative", change the settings, set the difficulty level to low and select the map "classified". launch and shoot the bots. bots will be counted as players. that's it!

More details

If in more detail, then take the support fighter "Irishman", in "devices" take a box with ammunition, and take a smoke grenade, well, and the gun that you want to upgrade, then go to the map shown in the previous section.

1. Place shields as shown in the screenshot below (so that bots cannot pass):

2. Go to the point shown below:

3. Throw smoke and kill bots, they won't be able to climb up to you (only occasionally).

4. Everything is ready, stand and shoot bots until you upgrade the gun, then you can choose another one, you can endlessly upgrade guns until you get bored, the main thing is not to capture points.

End

Well that's all the guide, if you have any questions, write in the comments, I will accept any criticism. P.S. this is my first guide
