Welcome to The World II: Hunting Boss, where you will kill bosses and that's basically it. You level automatically and there are no skill trees; this is bare to the bones. All boss fights are selected off a menu and there is no adventuring to be had...unless you count your eyes rolling to the back of your head. This game won't challenge you much at all and doesn't take much time to complete. That makes it the perfect game to pad your completed games count, gamerscore, and completion percentage.
For the simplest completion path, this roadmap will lay out some suggestions on when to do things. First of all, just go ahead and lose to the first boss ten times to Unlock "Heroes Never Yield." Then your next objective is to complete "Hunting Ace" as it becomes next to impossible once you get the AI companions. You will have also unlocked "The Rise of the Apes" for clearing the first mission.
Clear the remaining four D Rank missions to unlock "King of the World," "Sparkling Eyes," "Fresh Meat," "Hero," "New Talent," and "What a Collection."
Now before you head onto C Rank missions, you should grind your character up to Level 15. Be sure NOT to max them out to Level 20 since you still have to clear a decent amount of missions. Just repeat the final D Rank mission over and over til your desired level. Doing this will earn "Be Known," "Braving Winds and Waves," "Rogue Knight," "Excel the Predecessors," "The Blacksmith Lolita," "Violet," and "Fame Spreads."
Now that you're all leveled up, you can move on and smash through all the C Rank missions. After you complete the first ten missions you will be moved up to B Rank, but first, go ahead back down to C Rank and finish the last two missions. By the time you have done that you will unlock "Master," "Attack Damage Carry," and "Stop the Train."
Move forward to the two B rank missions and then replay Mission 2 eight times to unlock "The Brave." It's suggested to repeat this mission since it's easier than the first. If you haven't reached Level 20 with all characters by now, then go ahead and finish grinding it out on the final D Rank mission, "Steel Nightmare." "Make an Impression" and the "Legend of Hunter King" will unlock back to back once you hit Level 20.
This game isn't difficult or time consuming; rather, it's just boring. Fortunately, it shouldn't pose much trouble and will pad up your gamertag stats nicely.
