Finca lvl 17 destroyed in 4 seconds with unknown attack

[Pixel]

Hey guys

I'm trying to figure out what kind of attacks I'm getting that is destroying my finca in 5 seconds.
Here's an example

I can understand the 3-4 missiles but I have no idea what the first 2 "freeze" like actions are, I have the flashbang at level 5 but it does not make the same thing.

Thanks for the help
BTW Is there a user manual for this game? The wiki is not covering too much

They are using a skillset called 'Big bang'. This adds x% damage to buildings whilst stunned. The amount of damage depends on what level the skillset is. Skillsets are added to your sicarios. Have a look at your workshop for more info on skills. If you're taking part in the events then you will also have plenty of skills already to add to your sicarios.

Thanks. I guess those do stack up.
