For each level, I'm providing a map of the level.

There's no harm in playing them of course, but they're not necessary. Again, as mentioned, you do not need to beat the secret levels for any achievements. If there are two exits, then one will take you to floor 10, which is the secret level for that episode.

Each level has one or two exits that look like elevators.

The knife & pistol generally don't get used unless you have to (if you're out of ammo or just don't have a MG or CG yet). This changes a bit when you fight tougher enemies or larger groups of enemies, but if it's a couple dogs or guards, the chaingun tends to be overkill. The chaingun tends to fly through the ammo too fast.

Weapon-wise, some people really like the chaingun, however, I'm partial to the machine gun.

As such, I'll be encouraging you in the walkthrough to avoid these levels.

There are also secret levels in each episode, but you do not need to play them for any of the achievements.

There is a single achievement ('None Left Standing') for killing everyone, and one achievement ('Clean out the Castle') for getting all the treasure in a single level, but once you have both of those there's no reason (achievement wise) to go for all the kills or find all the treasure

Every map follows roughly the same pattern: blast your way through the level trying to find the exit, then take the exit.

Some of the later episodes can get a bit challenging.

You can save the game at any time, take advantage of it.

Often the easiest tactic is to run into a room, fire a shot off, then retreat back through the door you came in, then wait for the enemies to come running through & pick them off one at a time. Let's start with some general tips for the game:
