Jetpac Refuelled

Took me a few goes to get this achievement but i found it helps if you stay on the ledge at the top right, out of the way of trouble, rather than flying around all the time. Once you've built your rocket, only leave the ledge to pick up fuel and then return.

The hardest waves are the UFOs on levels 5 + 13 I found it easier not to shoot at all on these levels and they'll all bunch up underneath you, eventually, while you're sitting on your ledge. Only shoot the ones that don't gather under you and when you venture out to pick up fuel, fly from left to right, get the fuel and then, when they get close to you, fly off the left of the screen to reappear on the right. As they cannot follow you, this should give you time to drop off your fuel and fly back up to relative safety on your ledge.

The game will wrap back to level 1 once you've finished level 16 and the achievement will pop as soon as it does. Good luck.

Just like to add that each of the levels where you build a new ship (Levels 4, 8, and 12), you get an extra life.

You also get an extra life when your score hits 20,000 and 50,000. My score never got higher than 65,000 so I don't know if you get lives beyond that.

Also, once you get to level 9, the game "loops," in the sense that level 9 is just level 1 again, just with a different ship.

The levels (and enemies) themselves are straightforward enough:

Level 1/9: Blobs. These things fly in somewhat straight line patterns, but do tend to float towards the ground. Easy to avoid.

Level 2/10: Fuzzy Bastards. These guys bounce around, but the patterns they bounce in are easy to get around.

Level 3/11: Balls of Death. These are like the Fuzzy guys, but their pattern is fairly erratic at times. Be careful, as they can turn around or go up/down at any moment.

Level 4/12: Homers. These things, which look like missiles, appear on the left side of the screen and float up and down for a few seconds, until charging straight ahead, following your pattern. Easy enough to avoid or shoot down.

Level 5/13: UFO's. These seem to be the most infamous enemies in the game, and they have a nasty tendancy to follow you around. Even worse, they constantly spawn ON YOU. Keep moving, but don't worry so much about shooting them... it's tough, but you can manuever yourself around them. If you're going to lose lives in this game, it'll be on this level(s).

Level 6/14: Plus signs of death. KILLER EQUATIONS! Nah, these are like the enemies in level 2/10, in the sense that their pattern is super easy to read, and they don't move that fast.

Level 7/15: Arrows of DOOM. These guys are pretty much the same enemies you ran into on levels 1 and 9, but they don't decend at all. They move in a constant 360 degree angle, left or right. Easy as hell.

Level 8/16: Bouncers. I HATE these guys. If you played Refuelled, these are the equilivent of those guys. They have a similar pattern to the UFO's, in that they'll hover below you and chase you around, but they're easier to avoid, in my opinion.

Once you beat level 16, the game loops back to level 1 and BOOM! Achievement Unlocked.

Levels 5/8/13/16 are difficult and require a special strategy. The rest are pretty basic and can be done by staying near the top and constantly shooting.

Here's my complete run through the first 16 levels. You can see my strategy on level 5 starting at 4:00:

With this Strategie the Levels 6 and 12 should be way easier.

To begin with, you get extra lives by passing levels 4, 8 and 12 and also by reaching the scores of 20k and 50k, the most difficult levels in my opinion are 13 and 16

The strategy I used was to stay in the corner of the phase in most levels, there are levels that you need more specific strategies but with a little luck you can do it

Below is a video I made making this achievement I had already done it 2 times before recording the video, and I ask you to ignore the video with my hand appearing in the corner because it is not synchronized with the background gameplay

Sorry for the crashes, this was from a live I did, I hope it helps
