Lead your squads of school children in a real-time battle to capture the other team's flag in an epic snowball fight!

Each child has their own name, strengths and weaknesses, and sophisticated artificial intelligence so all you need to do is tell them where to move to, charge or rapid fire, and they will take care of the rest. They'll run away if you leave them exposed or surrounded so make use of the terrain and be careful not to let them get exhausted.

Play against the computer controlled AI or against a friend over Bluetooth or WiFi.

The tutorial map is fully functional and free to play, and if you enjoy it please buy the extra maps as an in-app purchase!

Very fun!

It’s free to try, and if you like it, there are more maps for you to try. Also, there’s multiplayer.

I like how much that it’s like Firefight but with children and snowballs, haha! I enjoy the all the strategic decisions this game presents. There’s a lot more than you might first think.

Here’s a bit about the game (it’s written in the game): there are different children/unit types that have different strengths. Children can charge the enemy to dislodge them from their position, but it goes wrong when the children lose courage when charging up hills and towards ice forts. The map set-ups allow for different plans. The maps are definitely not like each other, too, so there’s a lot to learn and enjoy!

Notes on the game:

I wish there were more maps, because 1 tutorial + 11 purchased maps are not enough. Although, I appreciate that the maps are very different from each other.

I love the different children/unit types and the charge ability!

Mortar seems ineffective.

I’m unaware of how exhaustion and (out of) breath affects the kids. I’m also not sure how to reduce those levels.

(Side note to developer Sean O’Connor: about Critical Mass, please consider enhancing the AI to avoid friendly fire and to avoid my range! I could destroy more units on the map given the chance, so I’d also like the AI to give me more opportunities against fighters. It’s also annoying that they run into me when I’m shaking an enemy. Edit: what about a second chance/life?)

Why are all of Sean o Conner's games like this?

The gameplay is very fun, but why the heck is this a freemium game? Sean O'Conner, you make some of the best strategy games ever, but all of them have the same issue. The only thing this game has is a tutorial. Want to actually play this game? Well your going to have pay 4 dollars for one of the several map bundles. And to the developer of this game, you make very excellent strategy games, but force your players to pay if they want to play more than 1 mission or a tutorial. 5 stars for gameplay, however the fact that this is a tutorial, and that this is pretty much how all the games from this developer are, I'm going to have to give this game 2 stars. Sean, if you are reading this, try to please add some free content to your games, like WW2 firefight. That would definitely bring my rating up to a solid 5 stars.

Can be good

So, to start off, I like the idea here but there is a ton of problems with this game.
1: The mortar has 0 effect on anything, I have not ever seen a mortar actually hit something.
2: The behavior of some of the fighters is plain stupid, I had an entire group of bullies and an entire group of regulars in a base, they were well rested AND they outnumbered the enemy I’d say 3:2, then the enemy which consisted of a couple bullies and a few regulars decided to charge and guess what? My team rolled over and let them take the base.
3: To be honest I’m not even quite sure what the problem is here but why are fighters on the other team always fading away and becoming invisible then reappearing randomly, they aren’t teleporting they just keep turning invisible, am I the only one seeing this, well anyway it would be great if they could NOT turn invisible.

Developer Response ,

The mortar may not kill many people as the enemy finds it easy to dodge them, but while dodging they are more vulnerable to being hit by a regular snowball. The incessant fire also demoralises the enemy. The latest release makes bases much more of a morale boosting feature (hills too) so kids are much less likely to rout from them now. Maybe your kids were exhausted and that's why they ran? The enemy fades out when you can no longer see them, and reappears when you can!
