Pterattack is a top down arcade flyer/shooter. Your objective is to shoot everything that moves, except for the huts. Use the space bar to shoot, and the arrow keys to move. That's everything for controls.
There are four weapons, and while others might have a different style, I like to go for the FireBall one. After shooting an enemy pterodactyl, there is the chance it will leave a power-up. There are four different varieties of these: PterShot (the blue one), FireBall (the red one), PterPod (the green one), and PterBoom (the purple one).
Your starting weapon will not work well later on, so whatever comes along, take it. If the first power-up you get is blue, go with it until the red power-up comes along.
If you go from one weapon to a different coloured one, you'll start at the bottom (the first level for that weapon). The only way you can switch weapons is to get a different coloured power-up. You can upgrade your weapon by getting more of the same coloured power-ups.
The PterShot is just a beam, and powering it up causes you to have more shots on screen, and makes each shot more powerful. The drawback for later in the game is that as a group of enemies comes at you, and you cannot move without taking damage, it becomes difficult to stop the advancing wave from taking out a life.
The PterPod starts out nicely. You shoot forward and to the sides starting out, which is good for taking out the Rex. The second form of the weapon shoots two balls forward off at a slight angle away from the center. The third is the same as the second, except the rate of fire is a little faster. The fourth form is a beam that, like the first weapon, is hard to use against a group coming at you.
The PterBoom is my second favourite. It's a boomerang-like weapon all the way through, though the shots don't return to you. Starting out you will fire a boomerang that moves back and forth a little bit in a random way. The second is like the green power-up, though it holds it twirls with the two attacks. The third is the same, I believe, not certain. The fourth increases the size of the boomerang quite a bit, so it can be easy to take out a group coming that would move just past you. A note of caution of the fourth purple power-up: Anything coming in front of you when you can't fire will likely hit you.
The FireBall, my personal favourite, starts out as a single shot. The second is like the green and purple as two shots forward. The third is different as it creates three forward attacks, combining the first two levels of this power-up. The fourth level of power-up creates three waves that move the same way as the third level, but covers and protects better. This is the reason the red power-up is my favourite, since it creates some defence. Also, it might take awhile to get up to level four for this power-up, but do not worry, I generally get it before I have 1,200 for a score.
That's the gist of weapons, though be forewarned, there are a limited amount of shots that can be on the screen at any given time. For the early-to-mid part of the game you'll generally shoot once, then only get another shot after you hit an enemy (for the shots that shoot at an angle, mostly).
Additionally, each power-up is worth ten points. Later in the game, it's not really worth it to switch weapons just for the points, but if there's a power-up that's the same kind as what you have, and you won't get hurt getting to it, go for it.
There are basically only two enemies, the giant Grarrl and the pterodactyls.
Grarrl: This is an enemy that comes stomping along from behind. He's the reason I would avoid being near the bottom of the screen, because if he is not visible then he is liable to come up right behind you and take a life away. Taking him out is easy enough unless being overrun; the only way to easily get at him is going near the wall. For early on when you only have a forward shooting weapon, wait until he is far enough in, fly behind him, shoot, move on. For later on, just be near the bottom of him, kind of on the side, and use a weapon that shoots at a slight diagonal and you should be able to get him. He is worth ten points for each hit, though he never actually dies and just keeps coming back.
The pterodactyls are your primary threat throughout the game. Over time, they become more powerful, and even make your weapon less effective, meaning it will take more hits to take them out. They come in these colours throughout the game: tan, green, blue, golden, red. There is also a white one that will start flying at level five and above, but comes from the left side (always from the left side) to bother you. This pterodactyl will not harm you, but if you're not careful, it can distract you from oncoming waves. All pterodactyls are worth five points, regardless of their colour.
The game is fairly easy in the beginning, if a little slow. You have the tan and green pterodactyls to deal with. The tan ones take one hit with level one weapons, while the green take two. You will also have to deal with the Grarrl, but he is generally not a problem. As time goes on, tougher pterodactyls come along with more frequency.
For an idle area, meaning where you should usually be early to mid-game, stay near the middle of the screen. After level five hits and the white pterodactyl starts moving in, stay near the right middle of the screen.
During the late game, I generally stay near the top of the screen to the right. With the level four FireBall power-up, it is easier to survive. Not too close though, since once the gold and red pterodactyls start coming, you are going to need room to move. So to clarify, if the game screen were divided into four squares, I usually stay in the center of the upper right square.
The main thing to remember is to keep moving, and if a flyer is coming down and you will not be able to take it out, move to the side if you can, since the flyers move faster than you do.
For the Grarrl later in the game, if he is on the left side of the screen, I generally do not bother. When he is to the middle or right of the screen, he creates too many problems, though.
When you have gathered a completely leveled weapon, make sure that you are careful not to grab any other weapon besides the one you have. By grabbing another weapon, you will reset your weapon level to one, which can have game-ending consequences in the later part of the game.
Final note on game play: Do not touch the walls, they hurt you, too. Okay, the final note is that the Grarrl stomping on the huts does nothing to your score, so don't worry about it. If you have morals against him stomping on huts, just pretend the inhabitants are out eating at a barbecue or something, far away from the pandemonium you are in the middle of. Better? Good.
