Gameplay-wise this is exactly the same as the 'base' game, which shouldn't surprise anyone. If you liked the base game, you will like this. My main gripe is its very short length: there are six missions total, but of those six, there are only three that I would say actually count as missions; two others are so short they barely qualify (~5 minutes without speedrunning) and the last one is basically a cutscene. However, the big missions we do get are very solid ones, with plenty of options available, and plenty of opportunities for all five characters to shine. Due to the length, I would urge you to buy it on sale. In all other respects it is more quality Shadow Tactics content.
*Game received for free TL;DR: The game is not incredibly unique and certainly has its issues, most notably the RNG, but when it works, it works; I certainly enjoyed my time with it. Immortal Redneck is a rogue-like arena shooter in the vein of Ziggurat. The aim is to get to the tops of several randomly generated pyramids, filled with various traps and enemies, by dashing, jumping and most importantly shooting your way through. When you inevitably die in this pursuit, you respawn outside, where you are given the chance to spend your accumulated gold on upgrades, new divine favours (classes), or boosts for your next go-around. The good: + Classes are simple and clear, and generally offer a unique enough spin on the same run-and-gun gameplay. +Environments and visuals are nice to look at. +The game has a nice variety of guns, ranging from basic pistols and shotguns to ancient Egyptian laser guns. The bad: - Most classes have decent or at least fun active abilities, but one or two -looking at you, Ammit- feel incredibly lacklustre. - Despite their variety none of the guns feel especially powerful, be it through lacking stats or lacking sound design. - You can come across random upgrades in the pyramids, which can be either fun (e.g.: chance to turn enemies into chickens) or incredibly frustrating (e.g.: you can't swap weapons until you completely run out of ammo), as a bad effect can completely derail your run. When the game allows you to play it, and you're zipping around the room, dodging and shooting enemies left and right, it's very fun. But when you're stuck with bad-to-mediocre weapons or some negative effect has you hobbled, it becomes an exercise in frustration. I did enjoy the majority of the game, but the game did not always make it easy.
