Alien Rage was met with mixed reviews upon release, with critics viewing the game as generic and prone to major glitches.
These points can be used to upgrade the player character, for example by boosting his resistance to damage or by increasing the amount of ammunition that he is able to carry.
The game was to be developed using Unreal Engine 3 by City Interactive's Bydgoszcz Studio, and would have a cooperative gameplay (co-op) mode.
[3][4][18][20] Daniel Shannon of GameSpot remarked that "If you have played a first-person shooter made in the last 10 years, then you have already experienced most of what Alien Rage has to offer.
[4] Reviewers especially took issue with the lack of creativity in level design, which Destructoid's Jim Sterling called "tedious corridors full of identical, monotonous, brainless combat encounters".
Sterling ran into two situations where glitches would not allow him to progress without restarting the level,[18] while Sam Turner of The Digital Fix experienced dramatic drops in frame rate during gameplay, and crashed to desktop several times.
While Kintner expressed a desire for additional, objective-based, types of multiplayer, he praised the team deathmatch mode's intensity.
