Image Description: A few years back there was a small points tournament at a local game shop that featured custom battle scenarios. Among them was the Techno-Zombies mission that took place on a desolate desert waste land with sand storms and surprise attacks from the before mentioned monsters. On paper it sounded really cool and everyone was really excited to try the mission, unfortunately when it came time to actually face those mechanical terrors well... I think you know what happened.
It just goes to show that if you're going to create NPC's for a scenario that you really have to test out the rules you give them a head of time and make sure that they aren't more over powered than any currently in print codex...
