Klei Entertainment has brought the world of gaming some truly wonderful gems. Invisible Inc. is one of those gems.
The gameplay consists of 2 distinct parts:
1) Management of your spy network (upgrading, choosing missions, selling/buying equipment)
2) Tactical turn-based missions
While the meat of the game lies in the second part, it is worth to mention the management aspect, as it gives a lot to the atmosphere of the game. You resource management at higher difficulties will get taxing and sacrfices will have to be made. This ties in nicely to the theme of a broken organization on the run.
The tactical turn-based missions are the meat of the game as mentioned and the meat is wonderful. Stealth is highly encouraged, as enemies remain knocked out for only a few rounds and killing them raises the alarm level, making every turn spent on mission more dangerous as the timer keeps ticking up each turn. Thankfully the stealth system is good and your agents get a generous amount of gadets and skills to use. In spite of that, the gameplay can get repetative on longer playthroughs, as the mission variety is not stellar.
The visuals of the game are wonderful and have the distinct Klei Entertainment style, with everything having a handdrawn look to it. Often times it feels like watching/being a part of a visual novel. The game is set in the not so distant future and has a great cyberpunk aesthetic.
The campaign is very short, as in you can complete it in a few hours. However, it is important to note that the game is built around replayability, with modifiers that can be added or substracted to tweak your experience. In addition the game does have an endless mode.
In conclusion, Invisible Inc. is a very good tactical turn-based action game with RPG elements and a classic cyberpunk story and setting. I suggest picking this game up if you are looking for something to play in short (0.5-2h) bursts e.g. while travelling.
