Yes, this isn't very original but I think it'll be pretty fun with all the different maps that the community has already built.
Stuff like the airport, or perhaps someone builds a remake of Dust_2. Plus we don't have to use the same guns, although they would probably have to be balanced.
For anyone who doesn't know the bomb gamemode:
a team of terrorists must plant a bomb in one of two specified locations. Another team of counter-Terrorists is sent out to 'counter' them. If the bomb explodes then the terrorists win, even if they are all already dead.
If the terrorists die before they plant the bomb then CT's win.
If the CT's defuse the bomb then the CT's win.
Defuse kits can be used to defuse the bomb in 5 seconds rather than in 10.
Money is issued out to each team at the start of a round, the amount depending on their current standing in the game (i.e. if you lost last round then you get less than the team that won), and the money is spent on different weapons and equipment like HE grenades and said defuse kits.
Each person in the team has their own individual pool of money.
Money is earned on kills depending on the weapons used.
If you're unsure about something, then just go wiki it.
But seriously it'd be pretty cool to see this get done.
