Maintenance - i have to figure it out, how to reduce that Security level to 45% in order to get to those doors and to obtain code to Relay Analyzer.
Executive - i chose to leave Groves alone (for now) and explore an Executive deck. Four codes appeared in monitors (those codes can be useful later), cutting down many Exec-Bots on my way, getting Railgun (it looks like weapon for big baddies), and finding out that Diego sold out the others for power - the history is getting more interesting.
About Exec-bots - good thing is that they drop (pretty often in my case) few shells for Shotgun and few 9m rounds, even 5 each of these, if i'm lucky enough. A penny saved is a penny earned, as they say. I'll start next part with Cyberspace sequence.
