Much like a trustworthy chain of command, realism in video games is hard to find. Battlefield comes close, but it's still got a few too many 360-no-scopes to get us there. That's where a game like Post Scriptum, a WWII-themed, first-person, simulation shooter, comes in. The game's slow pace with spikes of high-octane danger make it gripping and tons of fun.

When you think of military first-person shooter games, you probably think of Call of Duty — and if that's your cup of tea, more power to you. But if you're on the search for something that'll get your blood pumping with tension, you might find you enjoy something like Post Scriptum more.

Leaning heavily on realistic scenarios, Periscope Games has created something undeniably cool. Here's what makes it so realistic:


1. Challenging combat

One of the running jokes from players is that the enemy will be patched in with downloadable content somewhere down the line.

That's because even when you're getting shot at, you often can't see the enemy. Just like in real life, there are no clear indicators of where the enemy is shooting from. Also, you're using iron sights, likely to the praise of older veterans, so it's challenging to engage in combat in open terrain.

Smoke and gunfire but no enemy in sight.

2. Tactics are a necessity

If you think you can charge at an enemy position and win on your own, think again. Communication, cover and movement, and fire superiority all make the difference when taking ground.

Be careful about how you pass over open terrain.

3. The environment can slow you down

If you're sprinting through a field and come across some bushes, your character will slow down as you move through them. It sounds silly — in real-life you could probably charge through them — but you may want to consider crawling through them anyway, so you don't suddenly become a 7-11 on Free Slurpee Day.

Bushes are a real inconvenience in real-life as well.

4. You have to drink water to regain stamina

Much to the joy of Navy corpsman and medics everywhere, the game forces you to drink water. If you use the "sprint" button, whether you're standing, crouched, or crawling, you'll lose stamina. To regain it, you have to pound some of that good ol' H2O.

Unfortunately, changing your socks has yet to become a feature in video games

There's a happy corpsman somewhere...

5. There is no minimap

Most modern first-person shooters feature some sort of minimap in the corner of your screen that highlights objectives — but not Post Scriptum. If you want to know what's going on, you have to pull the map up. Even then, your squad leader has to mark things down for everyone and actually communicate things.

Best of luck to those new Lieutenants.
