I dun it now.

in the ice tunnels there are three major characters u must have:1)Iceman 2)wolverine
3)storm
do not use wolverine.use storm.but remember not to lose Iceman.when there are many
opponents use the whirlwind attack.Iceman is useful to construct bridges.he has to
construct bridges only 2 times.after both Iceman and storm die use wolverine.when
wolverine has less hp, stay away from enemies so that wolverine can recharge his health
