How to unlock the Old School achievement in Serious Sam: Siberian Mayhem - Definitive Guide

Can be completed on Tourist. Not much of a chore if you enjoy FPS games. Picking up S.A.M. skills is unavoidable and is also recommended for the Veni, Vidi, Vici acheivement. Just remember to NOT hold A in the Netrisca interface so as to not learn any skills before the final fight, fill your boots in preparation for the final boss.

Would also like to note that you can use equipment and unlimited ammo I basically spammed the hacked drones and mini nuke through this playthrough and for the boss fight just spammed the hacked drones and the boss will die really fast.

Should the first playthrough be done with this achievement in mind?

About how long does it take on Tourist (Easiest) difficulty?

If it's important to mention another achievement in the guide, consider adding the explanantion as to what it entails. This helps in case we need to know to follow 2 guides during a playthrough. Thanks.

Veni, Vidi, Vici
Beat the final boss in Singleplayer on Serious difficulty without loading mid-battle savegames.

I hit D-Pad left. Then tab to S.A.M.
I never "Learned" any of those skills and played through every level. Beat the big fire skeleton....
ACHIEVEMENT DID NOT UNLOCK.

Any ideas what went wrong?

Thanks.

UPDATE: Achievement unlocked on my 2nd playthrough to get all secrets. I think I had restarted a level from level select and not from my save.

The video guide for all secrets is very well done. On your first playthrough, I recommend following that guide while not using any S.A.M. upgrades. Easy and fun.
