I've been playing FPS a lot for a few years now.
For me, on of the most important feature in this kind of game is the "feeling" of the weapons. I like to "feel" when I hit my target, to "feel" each bullet I shoot.
That's the main reason why I dislike Counter-Strike, for example. The weapon feeling is just terrible.
On the other hand, some games, like Killing Floor or Urban Terror, managed to create really enjoyable weapons.
I just discovered about Unity and IM, and I have to say I didn't hope much of this engine (and this game).
But I tried Bullseye. And... wow! That's some awesome gun control you got there, guys.
If you can get through and release the game, while keeping the feeling of the weapons as good as in this little preview, it will no doubt be awesome.
I now look forward for the next updates to the IM project, for I just can't wait to be shooting at shark-tigers with this beauty of a SMG!
I also have great hopes for a multiplayer part, of course players vs. players but also cooperative.
I just can't give you financial support now, and I'm sorry about this. But I wish you the best luck in this project! I'm sure you will be able to get through it!
