About This Package
One Options is a spiritual successor to many familiar early flash games of the 2000's. In this game you wil find yourself alone against all odds. Kill the incoming waves of enemies. Each wave visit a shop and see what oppurtunities you can fund for survival. Buy guns, upgrade guns, buy defense upgrades and unlock shooters to aid in your survival.
FEATURES:
FEATURES:
- 7 Unique guns! Find the right gun for the right job, some do high damage at the cost of fire rate and mag capacity but others do the pew pew VERY fast and it's fun.
- Shooters! Automated shooters that will provide additional fire. You can buy weapons for them and equip those weapons onto individual shooters allowing a wide variety of weapon combinations as backup! Train your shooters to improve their overall stats so they can be more effective the longer you survive!
- Dynamic Wave Director: A Left 4 Dead styled Director that uses specific data to determine Enemies spawns. This means the faster you're killing stuff, the harder enemies you will encounter. This includes upgrading weapons and buying new weapons.
- Enemies have armor that will greatly impact how much damage your guns do! You Won't always see the true damage on them! Bosses have high armor!
- Hand drawn sprites, I used an Ipad and a Wacom Drawing tab and Krita software to draw. I'm not an artist clearly but it's fun drawing the animations in my free time.
- Full SHOP. Buy new weapons, buy Shooters and their upgrades, Buy base and wall upgrades, buy upgrades for your existing guns.
- 3 Unique enemies and 1 unique boss, more to come....
- Leaderboards! top the charts with your highest wave and most money!
- Difficulties, feel free to try out the multiple difficulty settings. Easy mode is for a casual cheese and check out all the game has to offer without any real challenge.
- 5 Unqiue Pickups! Killing enemies sometimes rewards you!
- A unique weapon Temper Gauge that gives your guns some flavor!
- Slame Reload your gun to get some minor buffs!
Everything is hand drawn, apologies for missing sprites, everything you see is a work in progress.
*IMPORTANT NOTE ABOUT LEADERBOARDS*
The current Leaderboards will be reset occasionally. This is due to the ever changing gameplay and mechanics. I keep thinking of new stuff to add and as a result I have to rebalance the entire game which means leaderboards won't be fair. Until the official release of this game, expect your leaderboard placement to get reset and also ignore "Experience" as some of my testing has leaked into the leaderboards and how S&BOX API works, I cannot manually reset my own SteamID, I have to wipe everything.
Feedback is greatly appreciated!
