Next game would be nice especially if you could position your units in, over, under,and behind the vehicles, caravans and animals for protection while attacking. plus crouch and prone for better accuracy.
2.5 3 fusion cores not upgraded, 1 accumulator upgraded, spam basic cannon and gauss (behind the basic cannon) on the farthest possible position from the base and spread evenly. 4 basic cannons very near the base in case of breach. pause as needed. VERY EFFECTIVE
See if it lags less now, I updated the game. :)
