This game is kinda challenging, but when you find out, how to play, it will become a bit boring. IMHO, strength-based agents are somewhat underrepresented. Intelligence-based agents are universal soldiers and doing all your job from obtaining diplomat's intel to exfiltration, while strength-based agents just used for exfiltrations with high threat level (which can be easily removed with diplomacy or agent with 7+ Int. and "hacker" trait) and capturing foreign agents (Which is cool, but not too cool to bring a dump-but-strong agent like Liberty or Shiva to your small team. A sole both-clever-and-strong-but-with-kinda-boring-traits agent like Wolf or Red Sword would be a better option, if you want to capture spies, question them and exchange them for a scientists or arrested agents) A small meme about game: There are two types of agents First type: Recruiter: Sigma will definitely make Earth a better place and *huge wall of text* Peace and Aiekillu: No! You are liar! No way we will participate in this щит Second type: Recruiter: We need to beat up some scumbags Punch: I'm in. Recruiter: By the way, we have drones. Gamera: I'm in too.

Currently, it is the only espionage management game I have found that flows smoothly. It leaves enough mystery and "randomness" to add significant replay value, as no two games are the same. There's plenty of wiggle room to make mistakes, but once mistakes start adding up, the difficulty skyrockets to the point where you're clawing at anything and everything to ensure victory.

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.
