Thanks to all for your comments
, it's being quite a complicated game to code due to the big number of variables but I definitely think that it's going to be a great game.
The shooter part is going to be very intense and violent, The player will have to fight to complete the main quest and secondary missions, and of course will also have to fight to protect his/her cargo B)
The way the attack waves will be formed depends largely on the game mode chosen, Adventure mode will be less violent and more directed towards the actual main T.I.M. story, there will be ambushes and similar nice things in this mode ( there will be heavy battles too when the story requires them ).
Arcade mode will be just a shooter mode with endless levels ( going to need loads of ships for this mode lol ).
The other available mode will be Mission mode, the player will have to carry out diverse missions in order to gain credit and credits, bigger ships, higher rank, and so on... Enemies will attack depending on the mission type.
As you can see it's going ot be quite a big project but things are going very well so far. I'll post more info when info is available
... I think that beertime has finally come, yipieeee!!!
