I'm genuinely shocked by how much I love ARC Raiders. I've never been very interested in the whole PvE (Player vs. Environment) genre, aside from some brief stints with Destiny, but ARC Raiders's sci-fi post-apocalyptic vibe just works for me. I love the Blade Runner/anime-like aesthetic of its environments, enemies and outfits. I'm a sucker for its synthy soundtrack and immersive soundscape.
"Those may pale in comparison to the new PvE game mode that was added with today's free update. Siege Mode places three players in the fight of their lives against endless waves of Tyranid and Thousand Sons..."
