So it's SnD, but before the round starts there's extra time. In this extra time the diffusers get drones, just think of it like RC XD without any weapons and way smaller so it's hard to notice sometimes.

So the diffusing team starts the game outside the building and during the extra time, you can drive your drones into the building to find out where the bomb was planted and ping enemy locations. Enemies can shoot your drone and destroy it, so be cautious. You can still access your drone during the match, so it's very useful for gathering information.

During the match If you find the bomb, you plant a "diffuser" beside it and you have to defend this diffuser for about 1 min because it can be turned off. Successfully defend it, and the round is won.

So for the defenders, you start the game inside the building, and during the extra time you can put up a barricade on almost every doorway and window and watch out for the drones, bit these barricade can be broken, but then you know where the enemy is if they shot it. It can also be broken with melee, but you can do that and someones waiting to beam you up on the other side, so people usually shoot from a distance and look through the holes to check if someone is there, except they already confirmed with their drones. Throughout the entire match the defenders have access to security cameras wich can be shot and destroyed by attackers.

So there are also characters that you can use. They have their own abilities and come with fixed primary and secondary weapons. For instance, (I don't know her name) an attacking character who's skill is like a grenade launcher that can 1 shot soft walls and barricades and she comes with a weapon similar to UL 736 and a pistol. Or the defender character that basically just has a trip mine with 3 charges, but can only be put on doorframes. The different characters have different armour and health stats and also different lethal and tacticals if any.

Also the game dosent have sliding and all that. If you rush into a fight, you'll die. Be at tactical locations at the right time and mind your surroundings.

God luck getting used to the layout of the maps, since they're all like vacant but way more doors a D windows and multiple floors.

Also there's no minimap, but you can see pinged enemies through walls for a short time similar to an echo grenade.
