Critical Mass is a game set in the future, where you are the commander of a squadron of spaceships. You will be sent on one of 40 different types of mission, ranging from protecting a convoy, to attacking an enemy starbase, to defending Earth.

You fight enemy spaceships using six different types of missiles which home in on the nearest target, so you have to be careful not to destroy your own friends...

The game is turn based, but with missiles homing in on your tail, enemy ships weaving to get out of your line of sight and sirens screaming warnings at you it can get pretty frantic!

My favorite!

I recommend downloading Critical Mass. I also recommend reading this review.

My settings say I’ve used this app for 10 hours in the past week. This is an awesome turn-based space dog fighting game! Despite having no tutorial, the game is simple and easy to learn.

Missions are played in quick turns. In a turn, the player adjusts the course of their ship, decides what types of missiles to fire, and can eject or use the “cloak” or “forcefield” ability.

Before missions, the player is allotted points they will use to assemble their squadron. Also, the mission briefing is given

After missions, the game reports the mission outcome and awards medals. The number of points for squadron building are determined by your level of success.

Here are a few tips I’d tell my past self:
- Be sure you don’t shoot your buddies down!
- Learn behavioral PATTERNS!
- There is more skill involved than you might think.
- Think about where everything will be in 2 moves (asteroids, you, friends, and enemies).
- You don’t have to fire at every chance (especially in later missions).

My best game just ended and lasted 14 missions, and I was awarded 2 gold medals (among others).

DEVELOPER: PLEASE add a way to mute volume and to review the mission briefing! Thank you for this awesome game!

Very Cool Space Strategy Game

I like this game as a slower turn based space dog fight game. I would love to see the ability to mute the sound and maybe add the ability to continue on the missions with an extra life or two. Perhaps at a lower level for those just learning the game mechanics. I love all my Sean O’Connor games.

Great game. Missing a few polish items

Great game. I don’t like that you can’t turn off audio.

I played this almost my entire 8 hours of flying. When playing on the PC, I don’t remember having to load up all 3 ship slots before I could go on a mission.
