Electronic Arts and PopCap Games today announced the “Tactical Taco Party Pack” for the bizarre console and PC shooter Plants vs. Zombies: Garden Warfare. The free expansion launches tomorrow, July 1, on Xbox 360, Xbox One, and PC, bringing players “south of the border” and introducing a new map and mode.

The new Western-themed map is called Jewel Junction and the game mode is titled Vanquish Confirmed. There’s also a new 8v8 mixed mode playlist that will include all competitive modes. In addition, players will receive two free custom character variants (with new appearances and abilities).

These new variants (Berry Spooter and Citrus Cactus) are sponsored by Aquafina Flavorsplash. This is not the first time a major publisher has teamed up with a non-gaming company to release DLC. Epic Games partnered with men’s magazine Maxim for a Gears of War: Judgment expansion pack in 2013.

Plants vs. Zombies: Garden Warfare originally launched in February for Xbox 360 and Xbox One, and came to PC last week. The game comes to PlayStation 3 and PlayStation 4 in August, with the latter version running at 1080p/60fps. For more on Plants vs. Zombies: Garden Warfare, check out GameSpot’s review.
