[1] In Double Cross, the player controls Zahra Sinclair, an agent of RIFT who can jump, wall-jump, and use her proton slinger to grab certain objects or get across wide gaps via anchors, and also has a number of combat-based moves such as punching, rolling to parry attacks and obstacles, and healing herself.

However, as this has led to negative consequences such as crime and contamination between worlds, a police force led by Valerie Wiseheart and Dash Sterling known as Regulators of Interdimensional Frontiers and Technology (RIFT) serves to maintain law and order between each dimension, with Zahra Sinclair being one of RIFT's top agents.

One day, a mysterious figure referred to as "Suspect X" steals the Metacatalyst, a weapon said to be majorly destructive, from the Extraverse.

In a post-credits scene, an army of the remaining Dashes decide to enact revenge on behalf of their jailed counterparts.

[7] Heidi Kemps of GameSpot gave the game a 6/10, calling the proton slinger mechanic "special" and "a lot of fun", praising the move's effectiveness and especially the time slowdown, but found the combat "a sluggish, simplistic affair", concluding "Had Double Cross opted to focus more on its strength--fun physics platforming--and de-emphasized things like combat and the tedious mystery-solving element, the game would have been an easy recommendation.

But the weak parts of the package drag down the whole, and Double Cross winds up feeling like it's a somewhat undercooked mash of ideas.

I’d love to see a sequel take the proton slinger and really run with it because there’s a lot of potential the game leaves hanging.
