I originally started this game as an expirement. the expirement was on video game addiction and seeing how you can addict people with them. My first test had no weapon upgrades and long levels. this was boring. i added the item drop to every enemy. this got boring fast. then as soon as i lowered the droprate it got more fun. it was giving you the feeling that every kill could be the "one". the next upgrade was shorter levels but more of them. this worked because of people's attention spans and if you beat one level you'll try to beat the next and the next and the next. try implementing these into your games i just barely implemented this but maybe a more hardcore programmer could utilize this.
I would like to see any game that you may have included this in please pm it to me.
Remember rare but very helpful upgrades/weapons and short mario like levels.
W,A,S,D to move. R and F to change weapon type (IMPORTANT)
mouse to aim and click to shoot.
P to pause.
Esc to quit.
Q to Assassinate.
Assassinations Require you to get up close but are more likely to drop items.
while an assassination is in progress you can still fire and enemys wont return fire.
You unlock weapon types by picking up upgrades with a green outline.(IMPORTANT)
Enjoy and please PM me those Games.
*Edit. Added Zombie Mode. bumps the 5.3 megs up to 17.5.
Whole lot more fun. complete with music from left 4 dead!
no assassinating in zombies. too glitchy.
