Description
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 46 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. Defend yourself with forcefields, or cloak to go invisible, and hyperspace out of there if things aren't looking good.
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!
After the mission you can replay the entire battle from the point of view of your or any of your squadron members' spaceships.

I have enjoyed this game and many others from Sean ever since discovering them as a kid in the mid 90s on a Galaxy of Games demos CD. Glad to see it come to Android! Here's hoping we see more ship variety added and a custom ship designer like in the desktop version!

Excellent game. I'm almost sure I played the shareware Windows version as a kid. 4/5 stars. I'd give 5/5 if there were in-game volume/mute controls, as I would like to play this whilst listening to a podcast or my own music.

Great little game, just ran across it again after playing it 15 years ago still challenging and fun

Difficulty scaling is pure stupid. You're continuously outnumbered and outgunned. Just not fun.

Edit. After some time, the game has become so laggy it is unplayable. Fix plea Amazing old 90s computer game! I played this as a kid. Loved it. Really worth the money. It works, a little laggy sometimes, not sure why. A quick force close, and it seems to catch up without losing game progress. The designer keeps up on updates with slay, so I imagine this will be fixed. It's distracting, not game ruining. If you ever get the chance, Mr. O'Connor, would you please make Rats work on Android? Thanks!
