You are Wolfgang the warrior. Mighty in Odin's army, you and your brothers have faught off invasion after invasion.
Now, however, the greatest foe you have ever faught has broken your army, and hounds the warriors as they retreatthrough the mountains.
But now, a chance has been given to your force. One person must stay in a high narrow pass, 
and that person must hold off the army persuing you long enough for your brothers to escape and regroup. So, as you take your position in the pass,  you know your time remaining on Midgard is short.
Your task is important, for should you fail, Ragnarok itself may be brought upon us all.
Controls:
s, j: attack left
d, k: attack center
e, i: attack up
f, l: attack right
qw, r, a, g, h,u, o, z, v, m .: Catch bonus
