Congratulations! You just won the Project ESC-3 Badge and 30 points!
Precautions is easily the hardest level in the bonus chapter, as a lot of it is luck. After that, it's not too bad.
To get the High Roller badge, you should note the following:
1) The best character for this is anyone with a counter (I used Duff). Master it, and it's like free damage points.
2) When you get 5 stars, throw your special without hesitation. You get 4 points per hit. Also, always throw a move after the combo ends. It connects often.
3) Do NOT counter a special combo unless you're sure you can win the showdown.
4) Most of all, blocking is your top priority. Do not get risky with your attacks/counters.
Good luck!
For those having problems with Challenge #6, the best thing to do is to grab the tiny orb and go right after a large orb. Shoot it, grab the tiny orb again (this means you'll have to take damage. Do it), and harass the smaller ones until you get more ammo. Keep doing it until you're really low on health; you should have lots of ammo to work with by then, but be careful, and good luck.
@huzzah: the "Destroy 40 objects" objective in Level 6 took a while for me; in fact, I got 39 four times in a row. What you need to do is this: you need a lot of time for the second patch of barricades. Get as far ahead as you can, get yourself as far to the left as possible (when you get to the second set of barricades), and then center yourself so that you plow through both rows at once. Then, keep racing, making sure you stay in front so that you can get as much as possible later. You can use the second lap for mop-up work. Good luck!
@Bandicoot: I assume you're using the hairpin to do this, and letting all the other racers go by so that you don't get hit and lose your skid. If not, do so, because the hairpin is sharp enough to get a good initial drift, and the lanes are wide enough to do what you need to do to get over 200, which is this: once you make the turn, slow down. Keep pressing up and right; that way, you'll still be skidding, but you'll be turning sharply enough to start doing donuts in the lane. It might take a few tries, but you'll get your 200.
Dude! You just completed the Overachiever achievement in Hanna in a Choppa and won the Overachiever badge and 30 points! YES. For those of you trying to get perfect on Level 8, don't try and fly to the right from the very bottom, because the fan's too powerful there, and even if you do make it across, you run the risk of hitting the wall above the flag. As for Level 20, if you pull the goo wall hard enough to the left, you can actually put yourself between the goo particles (which won't ruin your perfect if you hit them) and gently move out when the tower sways back to the right. Those were my last 2 perfects, and I hope this helps anyone out there.
"Dude! You just completed the Amberial Ace achievement in Amberial and won the Amberial Ace badge and 30 points!" I think I spent as much time on Tower of Glory as I did on all the other levels combined.
I think there's a glitch. If you hit the synergy bonus (for the first time) on your last tile, it doesn't count. I haven't yet seen what happens if you've hit it before and then again on your last tile, but it might be worth checking.
"Dude! You just completed the No Heartstone Unturned achievement in Hands of War and won the No Heartstone Unturned badge and 30 points!"
Jeez, that took forever. I WAS gonna go through with Ranger and Wizard, but forget it now. Still a very awesome game, and an easy 5/5 from me.
Just to clarify my previous post: for my Impossible badge idea, you need to get your castle to 100 height and knock your opponent's to 0 at the same time.
