There's an interview up over at
TenTonHammer with Global Agenda executive producer Todd Harris about the role of the Recon class. Here's a clip:
Turrets are really where the back and forth tends to happen in Global Agenda, because turrets are very powerful. If they’re placed in a good location, many times they’re going to need to be cleared out or blocked. Multiple classes may go after them and have different abilities to go after them, but recon can stealth behind them and use bombs to take those out. Often teams will place a spawn beacon inside an area fortified by turrets, so that’s a primary target for recons.
This Recon play style feels very much like the Spy from Team Fortress 2, except with better cloaking and no disguise.
