I tried to incorporate excessively used monetization models as mechanics in the game. So you use DLCs (Downloadable Content) to upgrade yourself, you have to get random improvements from Lootboxes, paid with virtual currency. As ammunition, you use your banknotes and there are a bunch of Live Services to subscribe to, in order to gain boosts (for a price of course). No worries though, there are no real microtransactions in the game. In addition to the mechanics just mentioned, I added other additional systems to make for a replayable, engaging and fun game.
In the full version, there are two different game modes available. There is a story mode, where you can make your way through a storyline. Your choices matter, as there are multiple pathways and endings. The second mode is the Custom Game mode, where you can set your prefered settings and difficulty and try to achieve better and better high scores. In this demo version, you can only play the custom game without setting your own preferences.
The enemies you face are Lootboxes with different attacks at their disposal. As you shoot your way through hordes of Lootboxes you earn DCs (Different Currencies – the in-game currency), which you can use to buy random rewards through Lootboxes. Those rewards are temporary improvements for this run only. During your playthrough, you also find so-called DLC fragments. You can use those to permanently upgrade different perks at the Centre (starting point of the level).
The upgrades include things like your movement speed, your fire rate, the amount of ammunition you can carry, etc. But with DLC fragments you can also unlock a new weapon and the ability to dual wield.
