Core Combat scored a 6.4 in GameSpots most recent review.
Core Combat's most obvious addition to PlanetSide is a set of new cavern areas for each continent that house "ancient technology"--a technology that powers special modules which provide bonuses when installed in a surface base. Additionally, ancient technology provides the expansion's new weapons and vehicles. The caverns themselves are quite large but consist of tight areas that don't allow too much room for vehicles, though they are connected by ziplines, a series of glowing lines that drag any player who is on foot from beginning to end (ziplines were recently made two-way transportation). However, the caverns are accessed by portals that periodically become active and inactive, so if you're "off-hour," you're out of luck. The developer has recently made the timer a bit shorter, though.
