Question: Does anyone happen to know which version the GOG one is? Is it 1.2?
Deadlock 1 uses patch 1.31 on gog, Deadlock 2 is patch 1.2. My normal experience with Deadlock is I have to restrict myself to a few territories to give the enemies a decent run. But for some reason with the version from gog, I noticed Tarth actually put together a mass of holocaust canon (4+?) to attack me. It was very impressive, compared to the usual few scattered units and lower tech attacks I've seen. Maybe it was just Tarth + plains, but I don't recall the AI doing that well against me playing Deadlock.
In the Deadlock 2 campaign, as Uva Mosk, I did get attacked. One level has the computer with much higher tech - you start out with nothing, and there's a few disruptor canon on the map! Good luck surviving an attack on a new territory against one of those! So if Deadlock 2 seems to easy, I'd recommend the campaign mode - hopefully it's not just Uva Mosk. It was very entertaining seeing uva mosk bonus + fast production bonus + map squares with enhanced production.
