On Serious difficulty, situations can become very deadly very quickly, the most important thing to do is to save, save after entering every new area, save after defeating a group of enemies successfully and saving some health and ammo, and sometimes just save for the hell of it. The button is your best friend, use it to make yourself a checkpoint even during combat and cutscenes. You should take each new area one section at a time, assess the area, kill the enemies with minimal ammo and do not get hit. But on Serious you're going to have to take your time, unless you're an expert speed-runner, but you wouldn't be using this Walkthrough if you were. On your first (low difficulty) co-op playthrough you need not worry about any tactics or health much. Serious Sam 3, like it's predecessors, is a very basic First Person Shooter, it does not rely on taking cover, flanking manoeuvres, or other tactics as much as on constant movement (strafing), saving, knowing where enemies are going to spawn, and managing your ammo and health well. The only thing that matters here is having '10' or '100' quick saves the game allows you to save anytime anywhere, so having a lot of saves to fall back on is useful, however, I'd recommend just keeping it down to 10 or, if you choose to have 100, regularly delete the really old ones to prevent glitches and framerate issues from having too many. I'd recommend you keep auto-save and auto-jump on however. You can change things, like the enemy blood colour, gibs (gory chunks of dead enemies), subtitles, crosshair etc, in the game options but none of them really matter.

In the controls I also found 'Vertical View Snapping' very annoying, and so I turned it off and increased the sensitivity, but this choice is yours. Go to: Main Menu - Help & Options - Controls - Controller Layout - Stick Layout and Button Layout. *Although you can't change the controls to how they were in the previous Serious Sam games, you can change some of them to suit you better:. = Netricsa: Enemy, Weapon and objective information
