Fun little game, but I ONLY RECOMMEND, IF it's on sale (3-4 Euros OK). After a first run, I learnt the basics, and lost. For the second run, I did some things differently and I won. Can be played through in 3-4 hours. 6/10

Fun story and mechanics, tension rises as time goes on. Simple to learn. Seems worth replaying at least 3 times to catch some of the tricks. Good music. Easy on my pc hardware.

I don't know how much I should recommend this, but I'm fairly addicted to it anyway, so I'm giving it a thumbs up. The plot is it is ten years in the future from whenever you start the game (neat little trick, devs) and you are one of ten global powers in a race to develop some crazy, world-changing technologies. You will use the disparate talents of your four agents to hack other countries, convince their scientists to come work for your country either through seduction, bribery, or a really good pep talk (or just straight abduct them) and then play a mini-game where you exfiltrate them out of the country. Meanwhile, your enemies are also developing technologies to use against you, deploying agents to steal your scientists, and otherwise being a general pain in the butt. Like most games of these types, once you figure out the optimal strategy, it's incredibly easy, but it's also good fun until you get there, and it's also fun to play less optimal strategies after that and see how well you do. Games are fairly quick as well, which is also a plus. Granted, from a balance standpoint, it's pants. High intelligence is vastly superior to high strength, hacking is ridiculously overpowered, and performing exfiltrations quickly and quietly is too easy, meaning your more gun-happy, violent agents are less viable. With some tweaking, this could be a much better game. It's probably not going to happen, but I'd love to see a sequel.

Amazing game. Looks a bit complicated at first glance, but if you give it a 1 or 2 hours to figure out all the mechanics, it gets very addictive. The story is also simple, direct but very enjoyable. If you like games like Pandemic or Orwel. It even reminded me a bit of the old Medieval Total War games, with all the spies and sabotage missions.

The gameplay is kind of mid but the atmosphere is actually really great and carries the game
