i got this as a gift a while back. i have to say at first its a little hard. most missions are timed and it doesn't tell you the path to go. it just tells your objective. for example, find and board this ship undetected. sounds simple right? not when your cloak runs out in 2 min and its a 12 min level. bottom line, you will either get frustrated from repeating the entire level 50 times from dying at the very last objective in that level. or get the hang of it. all missions are the "cat and mouse" (chase this) style: find this ship, follow this invisible warp trail or get to finish first before other ship does while avoiding collisions that slow you down. for $13 you cant go wrong. when i got it as a gift it was valued at $30.
