I was playing story missions to get my Titan to 20, and I'm currently finishing up the mission in which you awaken the eye of the gate lord on Mars. Out of nowhere, a Phalanx, jumps up, hits me with the shield and my character goes out of the map area, and promptly dies after. I've experienced this "super phalanx" twice now, and this is the first time it's killed me. While it may or may not be an issue, it certainly is something that needs to be looked into.
