Will anyone identify this old freeware game?

[Oberron]

I had this game in a CD from 2005 and I don't remember this game.
1. It is a side-scroller, much like the first two Duke Nukem games. (hint: the playable character's name shares with the game (not Game Maker) *insert correctly spelt first name* Rocket
2. The game came out in 2005, but it was completed in 2003.
3. Your weapon has two fire modes (three if you count the grenade launcher)
4. The enemies are tiny, green, and human shaped aliens, and also mechanical vehicles.
5. The game has three enviroments, from towns to the base.
6. It had tracker music, pre-rendered graphics and some decent sound FX.
7. Between levels, you encounter a boss.
8. You can upgrade your character.
9. It runs with Game Maker version 5.
Try to identify this and good luck.

Sweet Christ already. Alright buddy, listen to me and listen to me good.

People have lives. They will answer when and if they can.

You being pushy is not helping. You being rude like this is not helping. Lurk more.

Finally, I got an IDEA! It begins off with "The Ultimate *character name*", so I must say that I got it. Lock this one to the mods, please? Thank you.

To be fair, GooberMan's reply with only that picture was a bit dickish in my opinion.

FINE. Lock this thread, because I knew it.

Being a brat doesn't help either. The thing about asking questions on a forum is that we don't magically know the answer. Maybe only one person in our population of thousands knows, and maybe they don't get online very much. Maybe nobody knows. Maybe someone knows and has decided not to answer you because you're so impatient. It's impossible to tell for sure, which is why patience and politeness are so incredibly important around here.

Remember your Golden Rule? Treat others the way you'd like to be treated. Which reminds me: I'm locking the thread, since you seem so adamant that it be done.
