Deplete enemy's invasion forces and stop their offensive. When facing a large number of enemies, the only way to deter them is to use the powerful Haiphong battery.
We're under attack! Man the turret and shoot the creeps that are overwhelming the planet. Help is on the way but it'll take 100 more days. Can you survive till then?
Stop the invasion before the enemy reaches our cities! Alien life forms have been detected and our army has mobilized its defensive tower forces to protect us.
The clockworks are attacking! Use your turrets to knock out approaching clockwork enemies. Don't let them reach the source well before the day ends or the battle is lost.
