In extra mission 2,try using spawn on the first two stages[ Cor Caroli,
Er Rai]. On stage 1,use his Abomination axe and throw all seven of your
opponents [the axe takes life away for hits, not throws]. If that
doesn't work, use levitating attacks. On Er Rai, use the same axe and
mostly use levitation attacks because of the frequent earthquakes. The
Abomination axe is the best weapon for Spawn, I believe because, even
though it takes life away with every swing, [hit or not]when used
correctly, it can take over half of the opponents health in the first
strike. It also does not take life away from you when throwing an enemy
although it has the same deadly effect on them [a world of extreme
pain.]
