You mean kinda like Missile Barrage and Nano-Disassemblers?

I see Sins having a likeness to the Great War in the path that it is apparently taking. In the first game you see a fully geared up TEC, a still strong Vasari, and the fresh Advent. In Entrenchment all sides are set up for a stalemate and predictably not much ground will change hands, or it will change hands so many times as to make no difference. When brute force does not work, the next expansion will come in with more subtle options, like diplomacy and possibly more non-combat stuff. A third expansion would most likely be the Breakthrough where all sides are whittled down and something has to give. Whether it be a superweapon, new classes of ships, or the introduction of whatever is chasing the Vasari.

Something will end the war; it's just a matter of what.

I was thinking of bio weapons that you could launch and kill all the crew on the ship. then have your capital ship send in pods to capture it

this would be a good idea also mabey not bio weaps but boarding partys when a hull is breached could be a combines skill with the post above "mabey asulte team or such
