Sweet! In case you get bored I'm in the process of adding more concept requests (fresh stuff we've only discussed so far but can now assign with the good feeling that everything mandatory is pretty much done). For now there are the Spiker and a Pistol. I will also add map props shortly (air ducts, crates, door frames, …). If you want you could concept the latter as a prominent part of an environment (I recall you were interested in training your environment skills).
Also, here we go.
