Our hero is always ready to do some world saving stuff.
RTX comic, unlocked after certain level.
Electroscan will highlight all objects you can take or interact with.
Computers like these are common phenomenon on Mars, this is one way of interacting with your IRIS.
Aside from good looking and being able to commandeer all the bots, I.R.I.S. will be your guide most of the way.
Landing on Mars... or better say, crashing.
Whenever you get in/out, you'll have to wear an oxygen suit, and yes, oxygen wears off in time.
Encountering a colonist... that looks kinda out of shape. What just happened on Mars, did aliens attack by any chance?
Gliding down the ladder, much cooler than just climbing down.
Whenever lost consult maps, assuming IRIS has provided you some.
Infra-red vision will help you see enemies even through the closed doors and walls.
Using sniper to zoom in on some vermin.
Sometimes IRIS will need your help with circuits and signals to override something.
Thanks to IRIS, you can use this hover bot to reach otherwise unreachable places.
You have no idea how happy will IRIS be when she realises what kind of a body you got for her. Now she can turn on even the coldest bots, literally.
Hmm, looks like these rocks are blocking the way and I just don't have grenade strong enough to clear it, but what if....
You'll also get a chance to play some other characters you'll come across in the story.
When wearing the suit, you should always pay attention to the blue bar indicating your oxygen level.
At some point in the game, you'll equip your suit with a booster that will let you jump a bit higher.
But aside from being constantly running, Wheeler will get to commandeer several intriguing vehicles in the game.
Riding something... err, spider-ish, to climb over highly unpassable terrain.
With a bioscan you can see some souls not visible by naked eye.
Making new acquaintances, meeting new friends, the normal stuff on Mars.
One of the boss battles, against L.E.D. Battlecruiser.
Seeing how aliens communicate through light source, hence the L.E.D. name.
You'll run into many survivors on your journey, that you can save with your cube-storage thingy.
