Javelin Throwers (Men of the West) -- High damage, ranged attack, moves faster than scout. The only drawback is the slightly slow preperation time. Other from that, this unit is op. (Seriously, when you have 5+ of them, the charge button becomes a press-here-to-win button)
Guardsmen are hands down the best unit. They may not be the most powerful, but they're incredibly versatile and cost efficient. Deploy one or two with a skirmisher behind and you've got yourself a decent push.
It also happened with hydrogen and fusion reactors. One of my planets says it's using 110 hydrogen/second so I ship 112 hydrogen/second. Still ended up running out of hydrogen.
Cheslava, there seems to be a problem with the calculation of auto routes. I did the maths manually and found that my Tataridu (circuit producing planet) needs to receive 75,400 silicon every shipment, but the game says only 47,200 is enough. So, Tataridu ended up spending a lot of time not producing any circuits because it doesn't receive enough silicon.
Man, it sucks that we have to wait for so long for mission return times on higher levels. Deathmobile costs real money (I don't have a way of paying), so the game ends up being boring on the high levels. It's like playing for 5 minutes, then way for 50 minutes for you survivors to return. Not really asking to change, because I know you developers need money, just saying that it made me quit the game and overall rate 3/5, even though if I didn't have to face this issue I would rate 5/5, or at least 4/5.
