Sorry for such a late reply,
The series you might want to watch is
"STARSHIP TROOPERS THE ROUGHNECK CHRONICLES" it comes in 6 volumes but volumes 1-2 are mismatched but does really spoil anything.Its much much better than the movies in every way (theres no blood or ripped off body parts).It focuses more on Johnny Rico and the roughnecks told from a reporters point,who is attached to them.Its also closer to the book as well.
The entire series is CGI and for the time the graphics were ground breaking,but now are dated (my 360 has better).Some of the stories are great and all in all its great fun.
The Bugs are done very well and theres lots of different ones,which is great inspiration.The series even includes the skinnies from the book,its a great little series and much understated in my book.
I do not want to say much but if you want to get it check out either play.com/amamzon/ebay.(hope douglas does not mind me mentioning these!!).
The only down side is the way the series ends,very abruptly!!
Anyway i love the series and find it a constant source of fun/inspiration
Hope this info helps,
Cheers all 6mm
