Almost 500 hours I've played. Part RTS, part tower defense. Super addicting. Super hard. All it takes is one zombie to sneak in and destroy your whole base. You can spend 3 hours building a secure base but in the final wave have it all destroyed. I end up losing most games in the last day, but I don't consider loses a waste of time, but rather a learning experience. When I win, I move up the difficultly level and do it again. This is one of my all-time favorite games.

Play mission, lose, get reset back to the beginning. Play same mission, lose, get reset back to the beginning. Play same mission, lose to population goal, get reset back to the beginning. Close game, uninstall, never play again. Reinstall, open game, get reset back to the beginning.

They Are Billions is made for a specific kind of person, and that person is me: it's an RTS where turtling is not only encouraged but essential, where mistakes are severely punished and your base can be destroyed in the blink of an eye. And perhaps most importantly, this game lets you pause. There is no element of dexterity here, you can take as much time as you need to issue orders to your troops and micromanage every aspect of your play. If you lose despite this advantage, you have only yourself to blame... They Are Billions is not for the faint of heart. The title is accurate and you will be shocked by how many zombies that can spawn at once, and if even one of them gets into your residential district the infection will spread out of control. The stakes are higher than ever but that only makes victory all the more sweet when it is finally achieved. Two thumbs up from me, this is a game I will gladly revisit time and again.

This game scratches a particular itch that is hard to find. It's a turtler's dream - Build your base, capture every resource you can and climb that tech tree, because the game knows who you are and it's going to throw everything it's got at you and you better be ready. And frankly you wont be ready and that makes it so much more rewarding when you succeed. The killer feature of this game is (to my surprise) a pause button. If you're anything like me, trying to control hundreds of little units and navigating a mini map can get disorienting when the chaos hit. Being able to quickly pause to make some decisions and then unpause to see your plan spring into action is brilliant.

It is a fine game, but there is no mid-level save. I'm a working adult and I have limited time and this is by far the worst decision. Just such a dumb decision. Bad decision. Bad dumb stupid decision. You can just manually copy and past the saves folder on your computer to perform your own manual saves, but I shouldn't have to. I decided to play through the campaign because I do like RTS games and zombie survival games and this is a pretty cool combo. I do love how easy it is to get swarmed by one missed zombie making it into your base. This does not work well with no mid-game saves. pros: - challenging zombie mechanics that make protecting your bases from all sides very important - zombies cons I would like to reiterate that it is a very bad, dumb, poor, stupid decision by the devs to not have a mid-game save. Like, the worst thing you can do in a single player game. Just so stupid. I thought that 1 hour in and I still think that 100 hours in. The unit path-finding isn't great, plenty of times units start walking into walls or buildings. It works out fine most of the time, but it can be greatly improved. The required spacing between buildings is such a pain. Like, houses should be able to be stacked and your units should be able to just walk though them. Spacing quarries and sawmills is so tedious and difficult to get "right" and optimize placement. There are Hero mission that only give you research points, you don't get to use a hero on the normal levels. I don't get it. It is an RTS, not a point and click adventure game. So there is a whole skill tree for your hero that doesn't affect anything in the main game. It'd be more acceptable to me if you actually used the hero on your missions, or if you could train a "hero-unit" that gets increased stats from your hero skill tree. there is no way to speed up the game. Most level require you to last a certain amount of days and I'm prepared to win and hold off attacks by halfway through. If I could speed it up or even skip to the next day, that would be so much better. Conclusion Its just a fine game. I'm not going to play it again anytime soon and its hard to recommend to anyone who values their time. I kind of regret buying it, but overall is a well made game. Just a lot of decisions made that disrespect my time. I wouldn't have spent so much time on it if I didn't just want to give an honest effort. and a last note: It is such a bad choice to not have a mid game save. Such a bad, bad, bad decision.
