Watch PS4/Xbox One/PC Bombshell's New Boss Battle Trailer

3D Realms and Interceptor Entertainment have published a new trailer for their upcoming isometric action role-playing game, Bombshell, which is in development for PC, PlayStation 4, and Xbox One.

In this new video, Shelly "Bombshell" Harrison, does battle with an evil boss named Zeroth Guardian. This creature actually takes the form of a pair of beasts, who have ice-themed powers and are independently armed with a sword and a shield. You'll also notice that the boss battle plays out across multiple stages, and Bombshell must us her various skills and abilities--both offensive and defensive--to survive.

Bombshell must defeat this enemy, and the rest, to save the president from an "apocalyptic alien threat."

Here's the plot overview for Bombshell, which is every bit as over-the-top as you might think/hope.

"Once a respected bomb technician in the Global Defense Force, Shelly Harrison donned the codename Bombshell after she failed to disarm an alien explosive that led to the loss of her entire squad and her right arm. Deemed responsible for the resulting casualties in what became known as 'The Washington Incident', Shelly was stripped of her rank but later approached by a private military contractor promising her a chance at redemption. Harnessing the alien technology responsible for the dramatic turn in her life, Shelly became Bombshell--a tough-as-nails mercenary-for-hire touting a powerful bionic arm and a fierce attitude.

The game will be playable this weekend in Seattle during PAX Prime, where 3D Realms will also have on display a full-size scale replica of Bombshell's cybernetic arm.

Bombshell is scheduled to launch later this year across all three platforms. For more, check out GameSpot's previous coverage.
