This is not TDM, it's a full-fledged bomb defusal mode with an economy just like in CS. Money is represented by coins in your inventory, and loot is simply deleted upon death. Because of this, to save your money from being wiped, you need to spend it in a separate shop located above the player's spawn. The exact amount of money you spent will be refunded to you at the beginning of the next round.
To get the bomb, you need to interact with the laptop. If the bomb carrier dies, you can go back and grab a new one. T-spawn opens as soon as someone picks up the bomb.
