manual saves :/ thats lame
Strategy: You pretty much have to perfect every level because the points are so low for time and bonus and when you do get those points you should first buy weapons instead of upgrading your current one, overheat happens quickly and its better to switch between them until the cool down period is over.

Really laggy sometimes, but often not. Not very hard as long as long as "perfect" bonuses (not being hit in levels) is accumulated to get good upgrades early on.

Found spreader to be mostly useless as it is better to face enemies 1 on 1 instead of large groups.

Time stopper is absurdly overpowered. Makes boss fight a cakewalk, because it does recharge during use.

good game

easy medals

EAT IT. EEOYT.

You should probably do something to make it less laggy. other than that it's pretty good.

THE BEST TIP EVER!

RIGHT CLICK,THEN PLAY WHILE YOU IN MAIN MENU AND YOU WIN THE GAME.
