This game is amazing on so many levels.
First of all, the eye-catcher, it's very unique art-style.
Something which is by now expected of Klei Entertainment.
These guys pull out something new out of their hat for each title they create.
And Invisible, Inc. is no exception to this, standing out of the competition even on the first look.
There are even little details, like the A.I. which is helping you out getting more an more silly, as it's power-supply is dwindling throughout the campaign.
The gameplay is also quite unique in the way, that it's featuring two seeminly contradicting goals, first, be stealthy and careful, secondly be quick.
The game features a security-level which will tick up for any turn you make, but it will also raise if you get spotted by a guard, or if you are even killing a guard without certain preparations before.
If the security-level reaches certain amounts the stage will become harder, by adding new security measures like additional cameras or adding additional guards, sometimes with even better equipment.
Diving deeper into the gameplay, shows that the games rules are extremely solid.
It's not leaving any room for debate over an actions turnout was luck or the players own fault.
This removes a lot of frustration from the game, because you could never argue that you had just bad luck, or the game whould be cheating.
If something goes wrong, only you only have yourself to blame.
But the game has some problems.
The campaign is fairly short (about 4-5 hours per play through) and the story told is nothing even remotely as engaging as it was the case with Mark of the Ninja or Shank. Klei could certainly have done better than this.
Additionally the number a different enemies is very limited with not even a dozen different kinds.
But were Invisible, Inc. Shines is it's replay ability with 10 different options for starting agents, some with alternative loadouts and several different starting programs for your A.I.
Additionally the game features several difficulty levels, which limits your ability to redo turns and stages, as well as raising the security-level in more extreme ways.
But that's not all, it features a massive amount of different options to customize your own difficulty and even different modes aside from the campaign, like time-attack mode or endless mode.
So, in the end, the short campaign amounts easily 30+ hours of gameplay if you want to at least try out every mode.
