w, a,s,d, or arrow keys for movement, use the one you prefer to be honest, this is part 2 of my other game called "Gamble to get your dad out of prison!" although it is not essential to play the first game to play this game, I highly suggest you still do play it. (there is a flashback.) if you want to use a weapon, to use is to press the number on the keyboard, so to use the cheapest weapon press 1.
Credits to @Castle_Hippopotamus for giving me the boss battle enemy idea, if you don't want your model in my game send a comment under this game or message me on my profile and I will remove it. (THIS GAME IS HEAVILY BUGGY, REPORT BUGS IN COMMENTS.)
