- Community Price:
  - Community fair range: $0.00 - $10.00
  - Reasoning: The evidence indicates that users find the game to be of good value, with one review explicitly mentioning that it is worth it despite some aged voice acting. Another review states that the game is worth it even though it is short. The fact that the game is described as 'free' in one review suggests that users expect a low price point. Given the positive sentiment around the game's value and the mention of it being free, it is reasonable to infer that the community considers a fair price range to be at the lower end of the spectrum.

  - Game completion: 10.0h
  - Story completion: 5.0h
  - Session length: 0.3h
  - Endgame: N/A
  - Reasoning: The evidence provides direct and indirect indications of playtime metrics. The quote 'most missions take maybe 9-20 min give or take' suggests typical session lengths. 'My friends and I installed this game and finished it in one night (5 hours) of good co-op fun' indicates a story completion time. 'Very fun game for the first playthrough, however very short with just 1 campaign available' supports the idea of a short campaign. 'Despite how short it is, it will probably take you more hours to finish whole campaign, because even on normal difficulty, it can be challenging when you first start it' suggests that while the game is short, completing the whole campaign can take several hours due to difficulty.
