[@SimpleWriter] I laughed off-camera.

Still, the idea behind insta-crete is something I get from-

*Watches Greece soar by with a worried look*

-an old game called Scorched Earth.  You may've seen versions of it.  There was a 2D and 3D version, and players of it would find the Worms games reminescent of said games.  In it, there are weapons that basically launch dirt to bury your foe, thus making it harder for him to deal with you.  He's covered in dirt and - if he doesn't have the appropriate tools - he has to blast his way out, thus causing him damage.  Even if he CAN break out, he has to use up time and resources to do it.

In this case, the insta-crete-

*Greece circles overhead again*

-is a wad of quick-setting conrete-like substance fired from a weapon that's used to subdue a foe.  They get temporarily made into basically a statue.

*Pauses, thinking...*

Oh, right.  It's also like the Gloo Cannon from Prey.
