I'm starting to think... should there be a bomb for each team or just 1 bomb in the middle? What should it go up to? Any1 have ideas?
As for the bomb location, There are pros and cons for all kinds of different scenarios.
If you place it in the center of the map then all players will always know where the bomb is: Either in the center, in their hands, or in the hands of the opponent. This means if you don't have the bomb then all you have to do is find the other team's guy with the bomb and kill it, and the players switch roles.
If you give each player a bomb, then the both teams have to worry about how to get their bomb to the other persons base without losing their bomb in the process. Perhaps there could be a penalty (points, time, etc) for losing your bomb.
Another suggestion is randomly placing the bomb in certain probable locations of the arena using switches. This creates uncertainty for both players with them looking for the bomb and then having to place it all the while protecting themselves. If player 1 has the bomb, player 2 is still looking becuase he has no idea if player 1 has the bomb or not (assuming shared vision is off).
As for the number of points to win why not leave that up to the players (such as in FFA Hero arena maps). If this map is for two players you can give both players a civilian and put locations for 5,10,15, or even 20 points to win and the game doesn't start until both players agree.
Good luck and let us know when you get a beta version out!
