After having sprinted through the questline (which was absolutely awesome, with just the right difficulty that it was possible to do with a few friends and not having to look up any codes, please more of this, Bungie, that was BRILLIANT), I now have had some time to test out how the Simulant sleeper works on patrol. It's a Spartan Laser. For any fan of Halo, I mean this in the best of possible ways, believe me. You have one incredibly powerful beam, with a significant charge-up time, but unlike normal fusion rifles, these shots do absolutely not care whether or not it hits an enemy. It continues with the equal amount of rage and cuts through ANYONE. I've yet to find a limit on enemy bodies it can penetrate, as the highest number of enemies I've gotten lined up in patrol mode is 4. Ironically, Sleeper Simulant may be the most devestating weapon to clear "The First Firewall" with. I wonder if it's possible to wipe every straight wave of knights with it, due to the overpenetration. To me, it basically feels like a long-range, pinpoint precise, massively overpenetrating fusion rifle that will clear ANY hallway of dangers. Has anyone found an upper limit on penetrating targets, or found out how much damage it can do to a boss?
