* The action starts immediately as soon as you start your game. The first sight that will greet you are the Space Invaders. From that point on, the action will be non-stop with the only things changing are your rank and the difficulty of the enemies. Also, there is an interesting quirk in the game. If your ship hits a displayed score (after destroying some enemy), your ship will be destroyed. So avoid flying into scores. Also, you can only have one shot up at a time. This, though, can be countered by the fact that you can prematurely end a shot and fire another thus saving yourself a lot of time and perhaps your ship.

* Due to Gorf's limited hardware not being powerful enough to move the game's colorful sprites around easily, it's possible, on the Astro Battles screen, to slow the last two invaders down to a crawl; simply by repeatedly firing. On the Laser Attack screen, if you shoot all the enemy ships EXCEPT for the laser shooters, you can sit forever on the far left hand side of the screen. Useless, but interesting all the same.

* Astro Battles :
1) Fire immediately when the mission starts. You may get lucky and hit the Gorfian robot distributing the Space Invaders. Also fire at the invaders as they are being distributed for more points.
2) Instead of the normal 11x5 grid of invaders, you only have to deal with an 8x3 grid.
3) Instead of buildings to protect your ship, you now have a shield dome over you. It briefly disappears when you fire, but the invaders have to cut through it with their lasers.
4) Remember, you have a lot of maneuverability in your ship (i.e. you can go up and down) so it should be easy to avoid the invaders bombs.

* Laser Attack :
1) Your first priority should be the laser ships. Wait until they have fired and send a shot right up their laser cannon.
2) The escorts tend to make random movements so be wary of them coming at you from all directions.
3) As you advance higher in rank, everything speeds up accordingly.

* Galaxians :
1) Try to shoot the Galaxians when they are setting up to get the score for attacking Galaxians.
2) At first, only a couple will come down. After a while, though, the Galaxians attempt to swarm all over your ship. Since they each fire three shots apiece, this can present a particularly deadly situation.
3) Keep moving. There is no safe place (not even the corners).
4) At later ranks, it isn't uncommon for a whole bunch of Galaxians to attack your ship at once.
5) If you can, try to hit the Gorfian robot that sometimes bounds over the top of the Galaxians.

* Space Warp :
1) This is the mission that tends to kill off most players. You will see a black hole with dots in it. These dots represent the number of fighters you have to deal with coming out of the black hole. As a Space Cadet, you only deal with 12 fighters. From Space Captain onward, it will be 16 fighters.
2) Fighters leave fast or slow and rotate around the hole. In addition, they will also fire at you. It will take some fancy maneuvering to avoid both the fighter and the shot it fired.
3) Some fighters go around so fast, you just have to try to keep out of its way.
4) Sometimes fighters will launch a slow shot from the side of the screen. Watch out for these shots.
5) In the later ranks, it will take all of your skill to survive since everything moves very quickly on this mission.

* Flag Ship :
1) The Flag Ship will fly back and forth slowly. It will descend then ascend as it completes a back and forth movement.
2) There is a shield around the Flag Ship you must cut through to hit it. The Flag Ship can fire through the shield at you.
3) On the later ranks (starting with Space Captain), the Flag Ship is escorted by two Gorfian robots.
4) Plan your shots so you can expose the reactor. This will mean cutting through a little bit of the ship to accomplish this. Watch out for the debris you create since it is as deadly as the Flag Ship's laser shots. If you feel really daring, hit the debris for extra points.
5) After you have stripped the ship away from the reactor, a well-placed shot should obliterate the Flag Ship.
6) Again, in the later ranks everything moves much faster.
