Recently me and my friends have been using an unusual strategy on de_cache. If we unable to afford a full buy on T side, and we knew the enemy team could, we would force with tec-9s, deagles or SMGs, except one player (usually myself) - who would purchase zeus and body armour.

3 of the Tec9/SMG players would then attempt to push out of A main and secure A site control, which was often unsuccessful but could get an early frag on the enemy. Meanwhile, the remaining SMG player and the zeus player would walk into squeaky. One player would then put their back to the door so that the other may open it inwards (no idea why this works, but it does). The zeus player could then be boosted on top of the door and the SMG player would either attempt to push or bait a CT into squeaky.

As soon as an enemy enters squeaky, we is immediatey zeused by the player on the door. This not only secures a kill, but often an M4 or AK. The former zeus player then has an almost full buy at minimal cost, and can quite often clutch the round assuming that his teammates did enough damage and that he can engage each enemy individually.

Here's an example of me using the tactic. In this particular case it had an extremely good effect, and led to me getting a 1v5 clutch. Please ignore the background noises, I only realised I had been recording the quite inactive discord voice channel as well after I uploaded the video xD.
