The Egg Lancer looks exactly like Egg Beetle, but black in both versions. The Egg Lancer looks different between the Wii/PlayStation 2 and Xbox 360/PlayStation 3. In the Wii/PlayStation 2 version, the cockpit contains Eggman, and its claws are black with orange lines from the tip to body. Shorter yellow lines cut through the one long one like a pattern. In the Xbox 360/PlayStation 3 version, the ball where the cockpit was in the Wii/PlayStation 2 version is green, which changes to yellow, and then to red depending on how much damage it has taken. Its claw lines are red, not orange.
The Egg Lancer is the third daytime boss in Sonic Unleashed, and the game's overall sixth boss. It is fought with Sonic the Hedgehog, but can first be fought after unlocking its Boss Stage in Adabat's Gaia Gate, which can be done after completing the daytime Acts of Jungle Joyride. The boss battle takes place on a looping road in the jungle.
The Egg Lancer starts out by shooting missiles that leave a pillar of fire. Dodge it while collecting Rings. Should the player start the track all over, it will open its claws, leaving it open to attack. Then, it will follow the track up and the track will run sideways, with the camera focused above Sonic. The Egg Lancer remains behind the floor and fires lasers that move in a zigzag pattern. Avoid them. Then, when the floor ends at a rock face, the Egg Lancer will appear in front of Sonic. It then will slam the rock wall and rocks will come tumbling down. Steer clear of them.
Alternatively, the player can run right underneath the Egg Lancer's claws, miraculously not get hurt, and then a rock will hit the Egg Lancer and its claws will open. If the player finds themselves in a pinch, Boost into it to damage it. The path will then curve down and Sonic will fall down on to the track below it. On this track, the camera will zoom overhead, and the Egg Lancer will proceed with the same strategy it used with Egg Devil Ray. The player can hit it up to two times in this part. After this part, the player will have to do a Real-Time Interaction to jump along the pads, and if successful, the player will deal two hits worth of damage. if the player should fail, Sonic will fall to his death, thus starting the track all over. After this part, Sonic will fall through a hole and end up at the beginning and the Egg Lancer will repeat its strategy.
The time needed to "S" Rank is 3:30. Failure to make that time will yield a "C" Rank. Therefore, no Sun Medal will be awarded.
The Egg Lancer starts out by shooting lasers along the sides of the arena before opening its claws, which is when the player can attack it. It then goes up the path and hide behind the mesh floor below. Meanwhile, it shoots a bunch of stationary lasers. Simply Quick Step around them. Then, it will fire two lasers on the sides of the road that close in on Sonic before coming back on the road to attack Sonic with its claw. Boost into the Egg Lancer at this point before Sonic gets hit by the lasers. The track will then curve downward and Sonic will drop on to a platform below, which is rigged with lasers everywhere. Jump and Quick Step when necessary. After getting past that, the Egg Lancer will fire lasers and open its claws again. Use this opportunity to Hit it again. The player will then have to do a Real-Time Interaction jump pad section, where the last one is a three button QTE. If the player can do this, they will deal massive damage to the Egg Lancer.
On the second lap, the Egg Lancer will fire lasers down the middle of the track below. If the player stays in the middle, Sonic will actually fall a little to the right. After it is finished, hit it once more. When following the Egg Lancer back to the mesh wall, it will shoot a line of lasers while the top laser moves forward, followed by the next one, and so on. Before the laser in front of Sonic moves forward, Quick Step right. They will then move back, starting with the top. Quick Step right when the one behind Sonic moves back. It will then release a line of bombs that will move in a similar pattern. Repeat the process with the bombs, then boost into the Egg Lancer. When Sonic fall down to the next platform, it will be littered with fireballs in different pattern. Quick Step around them and hit the Egg Lancer again. If the player has taken every opportunity to hit it, they should can it off in upcoming Real-Time Interaction section.
The Xbox 360/PlayStation 3 version adopts some boss traits that were found in the Wii/PlayStation 2 version; you can no longer attack the boss freely and you can only attack him when he approaches you, you cannot hit multiple times, and the boss uses more traps and attack strategies.
In the Wii/PlayStation 2 version the Egg Lancer is controlled by Eggman, but in the Xbox 360/PlayStation 3 version it is controlled by what sounds to be Orbot and the Little Fighter robots that are seen in a few Night stages.
Eggman does not pilot the Lancer in Xbox 360/PlayStation 3 version of Sonic Unleashed.
This is the only Daytime boss fight where Orbot uses the same defeat quote as in the Egg Devil Ray: "Shucks! I knew this would happen!"
