Do NOT underestimate this game
Gameplay: Pretty good. Heck, really good. But it can get somewhat annoying always marching your units across the map. However, a lot of interesting things do happen along the way, such as encounters with tankers, emergency communications, etc.
They also brought the power armor to life! In the book, Starship Troopers, written by Robert Heinlein, all the troopers wore this power armor that increased your strength, was equipped with cutting edge technology, etc. Unfortunately, the idea was not implemented into the movie. But now, this game utilizes it. And it does so in a very interesting way.
Another thing that's interesting is the customization of... well... everything! You can choose your lieutenant's name, as well as your platoon logo and platoon name! Unfortunately, you cannot upload your own photos for a platoon logo, but they have a couple of decent logos. You can also change the names of all your platoon members. So if you wanted, you could name your men after your friends, and send them into battle! Or you can name your men after your worst enemies, and make it so they *cough cough* get cut off from the squad during a mission. Moreover, you can customize each troopers weapons and armor before he or she goes into battle, and whether or not you want him/her to be a specialist class, which are the medics, engineers, snipers, or psychics.
The bugs are pretty stupid sometimes. Like how the tanker always stops before spraying you with it's fiery evilness. As long as you keep moving your squad, it won't be able to catch you. Also, sometimes the bugs can start chasing you, but if you get away fast enough, they'll totally forget what they were doing and go about their business. Then again, maybe that's how they act in real life...?
As for your men. Their AI depends on you. You're the one commanding them, so if you send them off on a suicide mission, it's all your fault if they all die. What I thought was interesting, however, was that when the bugs start getting close to a trooper, he'll start walking backwards while still shooting. I don't know, I just thought that it was cool.
Graphics: Decent. Not bad for the time, but could have been better. Still, it won't kill you. Unless you're totally anal about graphics, it's fine.
Sound: Once again, decent. The guns don't sound that great, and the in-game voices is nothing to praise. What's weird is, when you order your soldiers to get into a formation, your lieutenant usually says something along the lines of "All right you apes, fall in!" (if you're playing as a male lieutenant) or "On my mark, fall in!" (if you're playing as a female lieutenant). But what's weird is their voice always seems to change every time you do it. Like it's a different person talking. You should be able to live with it, but I just thought it was worth mentioning.
As for the voice-acting of the Ensigns giving you orders during your missions. I think it's okay, but then again, I don't know much about voice acting. Everything is fully recorded, no reading on your part (except for the game overview before every mission, which isn't even that important to read unless you want to know the story).
Value: I'd have to say that even without multiplayer, it has pretty good value. Heck, I still play it YEARS after I bought it. I think the ability of being able to customize a lot of stuff in this game (and changing some of the files in the game to give you more stuff) gives this game much more life. Plus, some of the missions are just so fun to play. I mean, if you want to send your eighteen-man strike team to battle against the bugs, go right ahead. Or you can send in one man with two nuke launchers and see how much chaos he can create all by his lonesome.
Overall: Get this game, It's a little old, but get it, especially if you're a SST fan and can't play the newer FPS SST because your computer sucks like me. This is a really fun game that many SST fans will enjoy. It incorporates ideas from both the book and the movie, so all you people who were complaining about the lack of power armor in the movie, look no further than this game.
Oh yeah, and the fact that you can name a soldier after someone that really pisses you off and get him killed on purpose... yeah... what a stress reliever...
