Jewel of the Nile takes place after Wilson extracts Sam after destroying the Alcor Class Warship and activating both of the Sirian power generators for the Time-Lock. Scythian Witch-Harpies also appear more frequently than in the campaign. The RAPTOR Sniper Rifle and XL2 Lasergun are now regular weapons, instead of being hidden in secrets. The Aludran Reptiloid also makes a return, along with a new boss. It is basically the same as the Sledgehammer. In addition to three new levels, the DLC also adds a new weapon, the Axe. There's also a part where the player can use the Jetpack, which marks the first time it can be used outside of a boss fight.

Levels are mostly as linear as the ones in the default game, but there's one spot where the player can choose to do four puzzles in whatever order they like. Gameplay is similar to the base game, but there's more of an emphasis on using weapons such as the RAPTOR Sniper Rifle this time around. Jewel of the Nile contains three new single player levels, a new weapon, new enemy and a new boss.
