Not gonna say it's gonna be easy

Not terribly difficult to do in PT1 if you’re patient and play safe (it is much more challenging than what you’re used to because the enemies are actually the same level as you (this is true no matter what level you are in either PT). You only need to do the 5-rounders to get the skill point (the 20-rounders are MUCH harder, but in PT2.5 with good gear can actually be a lot of fun, especially in coop).
