Nick speaking,
After waiting so long for something new for Necrons, playing my first test game with the Necron Tomb Stalker was pretty exciting. So exciting in fact, that it seemed to have an effect on my gaming ability...
The Tomb stalker does exactly what you would expect it to do on the table, as long as you accept that in most games it will die! It does make a fantastic distraction unit that also can do some damage, giving your other units (Warriors) some breathing space. Necrons now have a nice new toy to play with, and I am looking forward to a few more games with it sometime soon...
