Infestation World

VS

Scum

Infestation World is a lesser-known survival horror RPG with roots in the 'Infestation' (formerly 'The War Z') franchise. The original peaked years ago and suffered reputation issues. Official player count data is limited. As an old, niche title with minimal mainstream presence and no major updates or publisher support, estimated daily players are very low.

Scum is a multiplayer open-world survival game developed by Gamepires and originally entered Early Access in 2018. While it is not a full MMO, it supports servers with dozens of players (up to 64 per server). The game maintains a niche but dedicated following and is frequently updated; however, it has never reached large mainstream status. Based on long-term trends of similar survival games, its daily active player base is estimated to be in the low thousands, and this estimate would hold unless a major relaunch or expansion revitalized the player base.
