Shadow X-3 is a Tier 7 ship in Starblast.io. It is the Tier 7 version of the Shadow X-2, yet shares a lot of characteristics with the Advanced-Fighter; it is a glass cannon ship which fires one frontal pulse with immense speed, damage, and knockback, as well as 4 small lasers from the sides. It is also the fastest Tier 7. However, the X-3 has relatively low shield capacity and regeneration compared to its Tier 7 counterparts.
However, its speed makes up for its low shield capacity and regeneration. Being the fastest among the Tier 7 ships, the Shadow X-3 is like the Shadow X-2, allowing this ship to go at high speeds and easily catch smaller ships. However, the Shadow X-3 has particularly poor agility making this ship difficult to use when asteroids are particularly dense in survival mode, as it is easy to lose health from asteroid collisions. A skilled Shadow X-3 can overpower tough enemies with pure firepower, so if you see a rampaging Shadow X-3, watch out!
However, note that U-Snipers and Advanced Fighters can mitigate the shield of a Shadow X-3 in 2 shots, making it essential for the X-3 to mine gems before duels. This is difficult as the X-3 is a terrible miner.
