Ranked in these QuestionsQuestion Ranking
Pro Rarely seen gameplay mechanic that combines multiple playthroughs
Each level is played through multiple times with every new playthrough adding previous playthroughs alongside current one. This is done 4 times trying to complete as much of the level as possible. It essentially creates a solo co-op experience and allows for lots of strategical planning forward.
Pro Vibrant aesthetic
The game has simple, clear, blocky levels and uses bright colors. There's an Iron Man inspired hud, but that can mostly be ignored unless you want to check out the score. Important information such as enemy count is displayed on the walls of levels and there's no need to keep track of health or ammo.
Pro Good weapon variety
The game has 6 different weapons that each has a progression system associated with 5 upgrade categories - Spread, Focus, Rapid, Punch and Acid. It adds another level of strategical depth as weapon upgrades have to be planned for.
Pro Level editor and Steam Workshop support
You can create your own levels to challenge yourself and your creativity. It feels really cool playing through levels you made, although you know what to expect.
Pro Anyone can download and play the game as it is free-to-play and open-source
The game is completely free and has no microtransactions or ads.
The source code is also free and accessible, so the game can be easily modded.
Pro Easy to pick up and play, even for beginners
The game consists of tried-and-true top-down shooter mechanics that will be familiar to most players; it is reminiscent of older arcade and console shooters.
Pro Easily play with up to 4-players in online co-op
Alien Swarm allows for up to 4-player online co-op, which makes for an easy way to play with a small group of friends or strangers.
Pro Convenient offline LAN support
Alien Swarm offers offline LAN (local area network) support, meaning that the game can be easily played locally with each machine connected together in the same place.
Con Abandoned support
Currently the game does not work with the retail version of the Rift, a DK2 (beta Rift model) and older drivers will be necessary to play the game. There has been no word from the developer if this will be fixed.
While there's definitely potential for multiple playthroughs to try and get a better score, the base game has just about 2 hours of gameplay.
Con Can get a bit repetitive
The gameplay doesn't change much from mission to mission; you’re generally just shooting aliens over and over again.
Con Gameplay is too short
The main story only takes about three or four hours to complete, which means you could beat the game in one sitting pretty easily.
