Gamer nerd historian pros, I call for your knowledge.

I'm trying to remember the name of 2 particular games. I bet someone or a few someones here will know them.  
 
#1 - In light of it being the anniversary of the guy who invented the hologram, I'm thinking of an arcade I used to want to play all the time as a kid. It was a big white machine, but the game was played on a surface in front of you and projected holograms before your eyes. I was very young so I don't know if my details are sketchy. I think the cabinet was white and oddly shaped. It was expensive and I wanted to play it so bad. I watched it a few times, and I think I recall it being like a series of quicktime events. I remember seeing it in many arcades in Southern California. 
 
#2 - This is an old PlayStation game. It was basically a top-down military style 2 player game. You would drive tanks and trucks around and do these capture the flag style maps. I don't remember much else.. I just remember I used to play it a lot and the only other game that got swapped into my system at the time was Loaded.  
  
Also, does anyone remember anything with the name "Iron Helix" ??  I had old videos for it on my Macintosh in like the mid-nineties. I remember computer graphics and I remember wanting to play it so bad.  

Anyone know the titles and have links???? IF you do, you're awesome and I respect you greatly. 

Wow I thought if anywhere, I'd find answers here.

I think number 1 may be Time Traveler

The second game might be Return Fire, which also appeared on the PC and 3DO. They even had a sequel in 1999 made for it. You controlled various vehicles and each one had Classical Music played while you moved it. 
 
I remember the name Iron Helix; the game may have been published on the PSX as well. They mentioned it in PSX Extreme magazine.

Wow, you guys are genius.  
 
Yes the first one was Time Traveler and the second was Return Fire. Return Fire was wicked fun. I loved it. Time Traveler... I never played it but I wanted to with all my heart and my mom would never let spend money on it. I"ve never forgiven her.
