16. Fontaine

This is the last boss, in case you didn't catch that.

Move forward after the ride and drain Fontaine of ADAM. After he jumps off
just unload five RPG's on him and keep moving in circles to finish off phase
one.

He jumps back on the machine, so take the time to switch to frag grenades.
Drain him again of ADAM. This time he summons bots to come after you, so hit
Fontaine with a frag and go left to the bot shutdown station and use it. Now
finish off this phase with more frags, so have good aim and be sure to only
shoot when you're sure he won't charge out of the way. So fire when he's
shooting at you.

He'll retreat again, so reload your frags and then drain him of ADAM. Now
he's to electric powers and now he's summoned his friends to help him.
Doesn't matter. Ignore the Splicers and keep launching frags at him. You will
probably have to switch to mines, so do that and keep the bombs flowing. Be
sure to keep your health meter in the corner of your eye and use a med kit
every now and then. Shouldn't be too hard, and if you ever need to switch
to your machine gun or crossbow to get in that last bit of damage, do so.

And that's pretty much it. Run in circles, dodge his attacks, and keep firing
your big guns. Don't really need your plasmids at all. Easy final boss, but
that's okay.

Now watch the final scene. This end scene depends on how you played the Little
Sister angle. Did you kill them? Then you get the war ending. Did you save
the little girls? Then you get the hand ending. Enjoy either one.

*NOTE: Rather than play again just to see the other ending, don't forget that
it's most likely one YouTube by now. I'm just saying.*

*NOTE: You could only get a few tonics from saving Little Sisters. So if you
chose the evil road, then you didn't get the Tonic Collector or Avid Inventor
achievement. Look over those achievements in my guide (at the bottom) and
then consider trying again.*
