Ivods suggested strategy is good, but for a defensive player like me it was impossible to use, for me a tactician with 5 missiles, 3 power boosters, 3 solar panels, 2 emergency devices, 2 SETA devices and 3 Advanced Targeting was more successful. This strategy needs a lot of anticipation and timing the secondary fire at the correct time for a trade off of more breathing room and making tough sections vs bosses easier.
@TheWitcher: Im finding the most effective strategy at later levels to be using the booster, drones and mines. Using only Drones make you not kill quick enough.
Great game, I really enjoyed it, its lacks some polish though, there are some obvious bugs:
If one have multigun on the three spots left, right, front, and a dissector in the back, the multigun to the right will dissappear in the shop menu sometimes.
The Dissector sometimes doesnt hit, like at all, I know this cause I have seen enemies standing within it without ever explode.
Sometimes the AI can be tricked by not moving, this will make the enemies stand in a ring around ones own bot, doing nothing. :P
And kindly disregard those saying that they will have less punishment from the game, I think its just enough. Not being able to keep money at the end of the level if one failed is resonable.
