Funny how it says you 'win', but if you wait long enough, another boss comes.
The joys of hell.
Its awsome, two people at the end of the game, w/ maxed out stats.
This has to go on
Go through once, and destroy every single enemy on every single level. Then go for speed, and only fight when you have to. For little/no damage, just take your time, get the Homing launchers, and just concentrate on dodging bullets. You can probably do No/little damage and a time trail at the same time. ...Hints ftw?
For anyone that said getting to level 20 of Survival is impossible, :P
