A possibility is to only have one terminal at a time open for capture, but have a timer for how long the hacker can hack it. Then when the timer runs out or the terminal is hacked the next terminal opens up and the round continues. Successfully hacked terminals give the attackers 1 points while the defenders get 1 point for defending a terminal for the amount of time it was opened. If a hacker is still hacking a terminal when the timer runs out, it goes into overtime for the terminal until the hacker stops the hack or the hack is complete. This also means rounds can continue on for extended periods of time without having to be reset to add another set of terminals.
Also, once we get arrows, maybe the hackers can hit their !voodoo keys to call for help if they're under attack.
Also, would be cool when the hackers were hacking they made that little keyboard typing sound Natalya did in the original game.
