Warhammer 40,000: Space Marine 2 patch adds a new weapon, plus some tweaks for the existing arsenal

"Where’s my Neo-Volkite pistol, Warhammer 40,000: Space Marine 2?" was my perhaps slightly ungrateful reaction upon booting the action game up after the previous patch. "I didn’t even know what a Neo-Volkite pistol was until five minutes ago, but now this whole game is trash until I get one!." As promised in the roadmap, the last big update added a whole new Operations map, complete with a gargantuan new pseudo-boss in the form of a hierophant bio-titan. It did not, however, give me my beloved pistol. It’s fine. It’s in now, along with a few, less Neo-Volkite updates to other weapons.

It appears that a Sole Arbitrator had been appointed in terms of the arbitration clause contained in the agreement dated December 5, 2018.

An application under section 17 of the Arbitration and Conciliation Act, 1996 (for short "the Act") had been preferred before the learned Arbitrator. Two Officers were appointed as Receivers in respect of the subject asset. The Receivers were directed to take physical possession of the said asset being an equipment being XR 220D, bearing engine no.22293605 along with its accessories, as mentioned in the agreement.

Pleadings disclose that the Receivers were not able to take physical possession of the asset in question as they were resisted by the respondents and the local police authorities also did not cooperate.
