I wish they'd keep doing their combos, it'd make it far more enjoyable than when they sometimes just crap out of it for no reason and decide to not combo for three straight waves.
A fun game, but the fact that you occasionally just lose complete control entirely of your ship, that's annoying. It's like the game intentionally doesn't wanna let you keep super mode. A few revisions and you got a topnotch, addicting, free-time-killing game.
Tips on survival: Cruisers. Nothing but cruisers, upgrades, repair bots, and control ships. Cruisers because they attack fast, are reasonably accurate, and have more HP than the strike craft and aren't silly like the missile craft (that I've found die before really even being effective). I have no idea how you're supposed to get to level 30 survival though. Once the missiles show up, god-awful targetting and unit movement make it impossible to stop the missiles with anything other than your face, which is, of course, counterproductive to winning.
This game is shit, your guys can't aim for crap, the AI is terrible, clicking on units is damn near impossible without sending others to move or attack. Not a good game. 1/10, it gets the 1 just because it looks decent graphics-wise, but even that is ruined by slowdown when more than 2 ships are on the screen fighting at once. Simply awful, retool this to actually play decently.
