Done in 4 with way more money than I needed. Step 1: Get very lucky on the first level after upgrading your launcher. Step 2: Only spend money on your launcher and rockets.
Haha @ xx1337haxorxx. I never thought of it before, but from now on I will be sure to show off all of my badges to my friends. I know they will be impressed.
So, say you have already completed the achievements, but your game needs to end before they count. Then, you click the menu bar, thinking maybe you can quit because the game is so easy that you will never die, but you are getting too bored to continue. At that point, if you accidentally hit new game, it sucks to be you, because you do not get credit for anything.
Got all the achievements first try. Just focus on collecting the yellows and getting the purples and dodging the reds. Don't worry about getting the point shapes that much, just make sure you stay far from where the shapes are coming so you can dodge the reds.
Bonus mode is ridiculous. Who the hell wants to go back through and replay only able to see the little circle. If you have a bonus mode, at least add a challenge or something. It's not much harder, just tedious.
Upgrades for units in game are weak enough that they aren't really worth it... Kind of weird for the fourth installment in a series where the same problem persists throughout. I generally do a lot better by just spamming low level units, even with the added cost of paving.
So, the top advice on this page is kind of rubbish. Two things made me play this game quite a bit better, at least in normal difficulty. First: Remember, everything you do not upgrade is recyclable for a FULL refund. Second: Waves come from the edge of the map and are not too quick. Together, these two facts make the game way easier. All you have to do is react to where each wave of enemies is coming from and build out lasers toward them, kill the enemy, then recycle and build in the direction that the next wave is coming. As long as you put repair stations with the lasers(which get a full refund as well) then you can sell everything back. The one time you have to vary this strategy is that you have to set up thel lasers to get mother ships. I beat every mining mission without using missile launchers and almost no laser upgrades using this strategy. You can even use this strategy to spam miners around each asteroid then sell them when enemies are coming and you need funds.
