I am so gonna stand tuned for the sequel and keep on making awesome games :D since all you can improve already has been mentioned luckily, would you maybe make after Haven : Sol sector a sequel where Sol strikes back at the Mahjouri?
Best part about the game was controlling the towers and owning the enemies... well as long as you had ammo. And who managed to take down an air unit with the artillery tower? That was my biggest feat.
Its Very COOL i love it, most of all i like how you can chose from different skill trees its very intresting mixing things up, like i did: almost every passive buff and then encourage, anger and perfection--> one hit more then 100 dmg for 3 round very effective. But to all who think this game is worth to be made a game for PS3 and etc.. rate up.Just love it.
game is good even though the hard visibility , but i like all the upgrades and the difficulty curve.
maybe add a upgrade for damage for all weapons and a slow regenerating shield would be nice and life increase execept for that 5/5
