Helpe find an old cancelled fps game

[Tecz]

So this game was shown around 2009 or earlier, it was a historical fps game that simulated bullet physics, you could set the game on different historical places, like WWI, I remember the devs were very young students, I remember a trailer in a setting like North Africa, I cannot remember the name they had a trailer and a preview with the devs, but the game was never released. The game had a lot of guns, all real guns from all history.
