is a FPS Survival and Action mix game set in a post-apocalyptic world where Russia is devastated by nukes and stuff which forces people live in the metro (Hence the name Metro 2033) but they are not the only one's there...
The game is really good as the survival part is crucial as u need to keep track of your gas filters... There is also some parts where u can either go guns blazing or use stealth to get past. The latter option is recommended as ammo is not that common to find which adds some realism to the game as the city/country is turned into a piece of ruins.
If u liked the S.T.A.L.K.E.R
series or the F.E.A.R
series then u will love this but Metro 2033 is more story-driven and has less open world elements but it adds some realism as there is nothing else to do in a nuked city with monster lurking around everywhere...
I might add more to this as I am a lazy writer.EDIT:
I did not see this coming how come I get over here... So I am going to add more stuff into this..
The Weapon system is limited but has different playstyles so if u want to go stealthily u may want to take a VSV otherwise u can go a Kalash.
In some levels where there are mostly monsters the shotguns come into play and u can either use a Double barreled duplet or go for a ubonyeg which has 6 shells but they are fired in some kind of a revolving method so reloading it might take some effort to get all 6 shells loaded..
There is also your knife as the default melee weapon which can be used as a last hope for survival otherwise there are many other weapons like throwing knifes, grenades, sticky grenades and other pneumatic guns to choose from according to your playstyle.
Like I mentioned earlier this game can be played both with stealth or with action... Stealth can help u alot in saving your precious ammo.. The stealth system is pretty easy as u have to just be aware of traps, broken glass and don't go into well illuminated areas or create some light yourself by either using a lighter, headlamp or even lighting the fuse of a grenade can give your position away.
The game has 3 levels of stealth. Green, Yellow and Red. Green means that u are completely hidden from them, Yellow means that someone have either noticed you or you made some noise, Red is pretty obvious they have spotted you and might be already shooting at you. U can see your stealth level by the LED Lights on your watch which can also be seen while holding some weapons. So you will not be putting your watch up all the time to check your stealth level.
The currency used in Metro 2033 is Military Grade Ammo which is hard to find and can also be used as ammo for some of your guns. They are much better than the Home brewn ammo which does less damage and is also known as dirty bullets.
The Military Grade Ammo(aka Golden Bullets) have a different look than the dirty bullets and since they are your only way to buy items & weapons u will have to really sure that u need to them in a battle or no since they can be easily wasted if u miss some shots.
I can easily recommend this game as it is just too good to try it out.It was bundled in the past and even given away for free.. Its not available on the store as the redux version is out which is just like a graphics update and maybe abit of tweaks and stuff..
The game is almost 4 years old now but the graphics is still good and there is rarely any bug that I encountered.. The game can keep u busy for around 50 hours or so even though the story is not that long but if u want to finish the game on Ranger Hardcore and get all the achievements it can easily take 3 complete playthroughs to get them.
