Central: What are you doing?!
This very vital part of your GUI may seem rather complicated at first glance, but really has only a few components. Moving outward from your ship in the middle, the first thing you encounter is a thin circle. This circle shows you the maximum angle at which you can use your secondary weapons if they are missiles. When aiming outside this circle, missiles cannot be locked onto opponents and rocket pods won’t launch. Going out further we encounter a similar, more easily visible circle. This one indicates the maximum angle at which you can fire your primary weapons. Remember, aiming further from the center of the circle reduces accuracy. Luckily, the game does not allow you to aim outside this circle at all, so your primary weapons can always be used. On the edge of the outer circle, triangles and circles may appear to indicate enemies and satellites, respectively. After this circle you will encounter two curved lines, yellow on the left, purple on the right. These bars indicate your weapon power (yellow) and engine power (purple). Weapon power is used up when firing primary weapons and railguns. Engine power is used up by boosting and by executing engine maneuvers. Both can also be drained by things like Ion Railguns. The last part of the GUI is next to the engine power bar. It indicates your relative speed. If it’s full of blue lines, you’re going your absolute fastest, boosting away. When you press no buttons at all, the speed will level out in the middle, while X will make you slow down to a standstill.
Top Central: How are you doing?
This part of the GUI shows the state of the game for both teams. It keeps track of both teams’ scores, the time left in the match, and in the case of domination, of the status of the satellites. The three dots around each of the satellite indicate the presence (if colored) or absence (if blank) of defense turrets. If the color of a satellite is flashing, that means it is about to be switched to a different color. Neutral satellites will be shown in white.
Bottom Left: This is you
Aside from the central part of the GUI, this one is probably the most important. This is the part that shows you how you, personally, are doing. In the middle of the circle it shows your ship and the status of its health, with green being good, while red… not so much. You might notice because your ship will be on fire. The circles around your ship are your shields. There’s front shields, at the top, and rear shields, at the bottom. Similarly, the color indicates the strength. In this case, blue is the best. If your shields get drained, they will eventually disappear, leaving the circles devoid of indicative colors. Of course, they do still restore themselves over time. Next to your ship on the right hand side you can find the power management. The F1-F4 keys are used to control where you reroute the power of your ship to give a bit of a boost to certain elements. The yellow bar is for the weapon power, the blue for shields and purple for engines. In the above picture, priority has been given to the engines using F3. Above both your ship and the power management, you can find the effects that are applied to your ship. Both positive effects (accuracy boost, deathmatch power-up, planted mines) and negative effects (interdiction, disabling of abilities) are shown here. In the case of the picture, this bomber has three seeker mines, a repair drone, and one railgun sentry drone laying around the map.
Top Right: This is your enemy
Once you have targeted an enemy, you can see the ship of your opponent here. More importantly, you can see which way they are facing. Their ship type is indicated twice, once by the red symbol on the top left, and once in writing below the ship itself. Next to the indicative symbol is the name of your opponent. The name below that is the name of the person your target is targeting. If this happens to be yourself, your name will be lit up in red as a warning. On either side of the target are the bars that show the percentages of shield power and hull health they have left. The shield power is in white on the left, the hull health in red on the right. The four triangles that surround the target ship are the same as those that appear around the ship itself in the middle part of the GUI if you have them targeted. They become orange on the inside if your target gets in range of your secondary weapons, while they turn red on the outside when they get in range of your primary weapons. The distance to your target is also indicated below the writing of their ship type.
Bottom Right: This is everyone else
On this map, you can see everything that your sensors can detect, plus everything that friendly ships can detect, as long as they are within communication range. This means that not only can you see friendly and unfriendly ships (little arrows), but also where things have been dropped (such as mines or repair drones). The different types of drops, however, are indistinguishable from one another, as they all appear as small circles. If you have targeted an enemy ship, this ship will appear as a red arrow with an extra arrow around it at the front. In the figure above, the target is just moving from D3 into E3. The power-ups, found only in deathmatches, are shown as grey circles with a lightning bolt. These are visible even if you are not in sensor range.
