Wave 17, was enjoying it. Then got beaten because I didn't draw a single yellow for 8 regular spawns, and then all of my extra draws (about 5) - ridiculous when a game fails THAT much on luck.
Guide for the hard badge:
1. Make sure you remove all lag. Restart the game, remove background apps, all of that stuff.
2. Using standard mode, and easy difficulty, make sure you can easily hit the spacebar with your spare hand without ruining your combo.
Now for the songs:
1. Two efforts for me on easy, 40k is a bit of a push on easy, but doable. Make sure you get 100% hit note, HOLD DOWN LONG NOTEs to the max, and use that star power. I got just over 40k on my second time (first time 99% notes hit and didn't hold down long notes that much and got 34k)
2. Probably the 2nd most difficult, keep a 4x combo going from the start for as long as possible, focus on the combo, which can mean sacrificing long notes.
3. Very slow, so keep the combo (which is easy without lag) and you should easily do this first time.
4. Same as before, but this song is surprisingly long, so you'll probably pass the 10k mark about 30-50% into the song to be honest.
Vote up to keep alive!
1 followed by your highest number then space will generate the quickest money. It's tricking the game into thinking the item you are selling back is worth more than the first item pressed.
Intriguing design flaw there by Mr Programmer!
@Werewing - his suggestion is for Colour Coded targets when you press 'e' - for example red for flamethrowers, green for nail gunners, etc.
And it would be a good improvement, it's hard to tell for the front rows who's who.
