Area denial is an interesting area in AF10. While landmines are still made (and due to less issue of lasting injury, slightly less stigmatized) they can present issues in tight spaces of transhuman construction, and risk infrastructure or even depressurization in enclosed habs. A mantrap can block a door or other route - but only covers a single surface. To this end, there is some desire for a device which can offer an expanded area of coverage to block doors and halls and hopefully cause less destruction than explosive traps. Luckily, materials science has solutions.
Web Grenade: While coming in grenade form, this device is more like a container for spools of carbon nanomaterial fibers, which end in grip head micro-anchors. When detonated (ideally in an airburst) the coils fly out in all directions to a maximum length of about 1.5 meters and anchor to surfaces, creating a web of black coils. These strands impede visibility, and are strong enough to be impossible for a morph to break under their own strength - they have to be cut with a tool, or the core grenade found and dismantled so the webs lose their anchor. Such a process can take several minutes, buying valuable time in a pursuit or security situation. Anyone unfortunate enough to be caught in the blast radius of a Web Grenade takes 2d10 DV with an AP of -5, and will effectively be grappled to the web grenade until they can extract themselves. This can be done as a Complex Action with a SOMx3 test, but causes 1d10/2 DV which ignores armor as the anchors are ripped out - or can be done as a more delicate proceedure over about 5 minutes (possibly requiring some form of Medicine test). This is available both as a minimissile and a grenade, but not as micromissiles, standard missiles or minigrenades. [Moderate]
Web Grenades are often used by scavengers and zone runners to keep away hostile exsurgents, TITAN bots or just fellow scavs by blocking narrow access points and delay long enough to escape. Some criminal operations (especially smugglers) also occasionally use them to delay rivals or law enforcement so they can get away. Military and security forces are also known to carry them, however, should they need to improvise security on a location with methods less permanent.
Addendum 2E: If converting to the 2E playtest, count the Web Grenade as Moderate Complexity. It still inflicts 2d10 DV, and applies Grappled status to anyone hit with it, and inflicts a d6 of DV which ignores armor if ripped out. They probably shouldn't be restricted, and also note the lack of the "Armor Piercing" trait. Any other aspects of Seekers and Grenades normally applies.
