Arknights Endfield Devs Warn Against PayPal Payments Amid Hack Reports

Arknights Endfield, a new free-to-play sci-fi action RPG from Hypergryph and Gryphline, launched today on PlayStation 5, PC, and mobile. Unfortunately, many players are reporting unauthorized charges to their PayPal accounts, creating a problem on launch day.




![The study demonstrates that shaping and optimization-based modulation schemes, specifically with a parameter setting of [latex]M=16[/latex], allow for nuanced control over a system’s behavior, suggesting that complex outcomes can be achieved by carefully calibrating these fundamental parameters.](https://arxiv.org/html/2601.15004v1/Figure_02_Constellations_Part2.png)


![A procedure designed to minimize breaks in data comparison-initially requiring 12 breaks-can be optimized through targeted merging of substrings, progressively reducing the break count to 6 by accepting a corresponding increase in omitted bits, with the most efficient merges achieved by prioritizing the shortest substrings-such as [latex]c_3[/latex], [latex]c_5[/latex], and [latex]c_2[/latex]-to balance computational cost and data loss.](https://arxiv.org/html/2601.14623v1/x4.png)
