The competitive mode is the has the same principle as the defuse mode.
The main difference is that a team is required to win 10 rounds to win the game instead of 8 and that the teams sides are switched after 9 rounds.
Another difference is that players required to buy equipment such as the defuse kit, vest and helmet, whereas in the regular defuse mode those items will be automatically in each players inventory at the start of each round.
The maximum amount of money a single player can have is 16000$ and all players' money and inventories reset after the 9th round, when both teams switch sides.
