Review Languages
 

Donut graph showing review languages for Alien Swarm and the proportion of players they represent.

This donut chart displays the languages of Alien Swarm's reviewers. The most popular language is English (47%), followed by Russian (18%). There is a healthy diversity in the review languages, with 28 different languages represented. The game has been translated in only one language (English), it's always good to have more translations to access other markets.

Time Played

Chart displaying Alien Swarm percentiles of time played for positive, negative, and early access reviews.

This chart displays the time played in Alien Swarm depending if the reviewer left a positive or a negative review. The time in game is not bad at all, with 25 hours in the 80th percentile.

The median play time for the negative reviews is 6.8 times less than the median for positive reviews. A low negative review time (median : 68 minutes) can mean that the game crashes on some systems or that the type of gameplay was not completely clear to the players (Is the game unmistakably explained on the Steam Store ?). It is also possible that players were otherwise displeased by Alien Swarm and decided to review it and get a refund under 2 hours. You could check if there is an explanation in the Players' feedback section.
