Roman Petriv, Yaroslav Rubash, and Gregoire Lourme's Trinitas is an action-centric defensive shooter that might be best regarded as a Sentry Knight-alike, only, y'know, left-sided rather than right. Your hero is in a tower they must defend, and they automatically fire wherever your cursor is pointed, with the number keys available to you to unleash special skills when available. Knock down enemies before they reach the tower to damage it, and use the coins they drop between levels to upgrade your stats and equipment. Eventually, you'll unlock heroes who'll fight alongside you, which is handy given the plethora of baddies that quickly show up to ruin your day. The difficulty still ramps up slowly, and as you might expect in any gold-based upgrade system, you may have to do some grinding to beat some of the more frantic levels. Trinitas is a solid game with a clean and appealing presentation, though it all might feel a little too familiar to some players. Not all of the upgrades feel as useful as they could, such as the way the knights don't always target what you want them to or deal much damage, ditto your "rain of arrows"-y spell, and it isn't immediately clear what the expensive bows do. Though some more enemy variety early on would keep things fresh, completing one campaign unlocks the next character to play as with their own enemies, abilities, and upgrades, making Trinitas a meaty chunk of gameplay for any fan of the genre.
