Level 2: Two Towers
Difficulty: Easy
The Laser is probably one of the most useful weapons in this game.
When there are lots of enemies lined up in one direction you can simply shoot once and take them all out.
It's also a great choice for taking out foes that are flying through the air since the sub-machinegun just forces them away out of your sight.
Though later on there are much more powerful enemies which take more hits to kill.
The boss in this level isn't that tough.
The laser attack can be avoided by circling him and the drill attack is all about dodging. Later on after you destroyed parts of this machine he'll get faster.
