Defeating Mastermold:
To defeat Mastermold, first use Wolverine and slash away at his feet and
jump when he steps. When the three Sentinel Controllers come out, fight them and
dodge Mastermold's missles by running in circles around the generators. When he
gets his shield, turn on the three generators and wait until it goes away. From
now on, use a long range fighter to finish him off. Remember to dodge the
missiles.
Defeating Sentinels:
Choose Wolverine (at a high level) and run behind the Sentinel. Choose the
Brutal Slash attack (R2 + X) and repeat it until the Sentinel falls.
Extra health and energy:
When you receive a new course in the Danger Room, do not complete it.
Instead, fail as much as possible. Every time you do the course, you will
receive health packs, energy packs, armor, etc.
The best way to get a extra utens is to fail the Danger Room courses. If you
complete a course, the next time you send in your team they will not receive
anything for their trouble. However, the first "final exam" as a freshman is a
very easy one. Just do not destroy the generators. By doing this, your team can
run around kicking butt for quite awhile and collect a lot of times. Note: Make
sure all your teammates are set to auto-refill their health at 80% (this can be
changed in the first field of the detail view for your characters). Also, watch
for the inevitable cut off time (about a half hour in). At this point, the
villains will no longer give anything up. Then, destroy the reactors and leave.
Make sure to sell Forge anything you absolutely do not need; otherwise about
halfway through your available time your inventory will be full and you can miss
out on some good items.
