Metro: Last Light

- Unlike Metro 2033, you can buy filters after the early game, and the ones you find out in the open are actually useful.

- Spend your Military Grade Rounds on ammo first and foremost, you will find a LOT of upgraded weapons during gameplay, and you should only upgrade the ones you really, really like.

- There are two endings, but you basically need a guide for the non-default one.

- Hold E for a silent, non-lethal takedown.

- There are two big difficulty spikes in the game, and they both involve defending your position while waiting for something to arrive. Don't worry if you are getting killed all the time, the difficulty evens out after those parts.

- Don't underestimate the Nosalis. They got a pretty huge buff from 2033.

- Wait for the last ten/twenty seconds of air before swapping filters.

- The Throwing Knives are incredibly overpowered, and you can retrieve them.

- Ranger Mode is not necessary, the difficulty levels are properly balanced. It's not like 2033 where Easy made everything a bullet sponge.

- If you are using an AMD card, turn off PhysX which is enabled by default. Your framerate will thank you.

- The Kshatriya mission in the "Factions" DLC is the closest we have to S.T.A.L.K.E.R in the Metro engine for now. It's really good.
