Once you figure out how the AI works, it gets fairly easy. Try to keep about 1 or 2 large groups of soldiers to hit an area hard or to slow down an enemy rush while having squads of 1 or 2 ninja cap bases. Try to get bases that are grouped together first as having the spawns closer makes them easier to defend. ALWAYS try to fight from your bases.
Easiest way to win is to max out the reload skill (makes all reloads instant... including the vulcans) and use the AA-12 (secondary doesn't matter... would not recommend using secondary), for perks have fast shot, piercing shot, and powerup magnet. Using that combo, I completed the final level on the first try.
Very well thought out game... interesting beginning... and all around fun game...
For those of you having problems with lag, turn off the particle, smoke, gore, and explosion effects
5/5
So much fun.... Wonderfully designed.... upgrades, hotkeys, and storyline would add even more.... random death glitch on lvl 3 when you shoot too fast kinda annoying.... love when game lags while using shotgun and random wall of bullets appears and clears the screen.... XD 5/5
Very well crafted game. It was extremely enjoyable to play multiple times. I do agree it would be better with more upgrades, more ship choices, and a campaign. It will be hard for you to top this one, but i hope you do. 5/5
