I got killed by a det pack through a floor twice,
Russian Japan it showed the player above me
The player would have had to run down the stairs, move through a room into a third room set the pack, move all the way back and detonate the pack. Or throw the pack in the floor and detonate killing me on a floor below.
Any chance he placed the det packs before you entered the room? Were you playing demolition as the attacker?
Next time you’re on defense, place some tnt on the obj. When the enemy starts to arm, you know what to do.
Unlike AP or AT mines, TNT charges cannot be shot or set off by other explosives. So if you have a 6 man squad all armed with TNT, that is 6 individual traps.
Also, if all 6 are stacked onto an indestructible surface, 1 being detonated will not affect the rest.
If stacked on the ground however, the first will create a crater, causing the rest to despawn. But if placed far enough apart, no issue at all.
I could be wrong btw. Unsure if the enemy has the ability to shoot or blow up your TNT charges.
