Zero Caliber 2 is an all around better game, but if you already played it, then this is still fun. Something that would have made this way better is if horde mode on multi-player player could be done solo, while other join while you are actively playing. This is something Zero caliber never did and would have bumped this up greatly, but they chose not to do that. Instead, nobody will wait around for hours watching a static screen until someone may join your game.
Just finished the campaign and I wanted to present my thoughts on the game. This review does contain spoilers for the gameplay and story, so be advised if you haven't played yet. Positives first. The game is very arcadey, which I like. Enemies are bullet sponges and usually take a few shots before dropping, so fights are usually extended. The gunplay is.. alright. I did struggle reloading a few weapons (SCAR, P90) due to the weirdness of the bolt interaction, and shotgun reloading is a little underwhelming (the sequence of putting in the shells is animated and automatic), but I did learn to respect it. And there are quite a few enemy types. The ones I can remember off the top of my head are: - Small Ballistic Shield - Enemy Ballistic Shield - Rocket Troop - Sniper - Shotgun Rusher - Machine Gunner - Drone - Helicopter - LAV - Heavy Minigunner - Heavy Launcher - Heavy Sledgehammer The enemy types in this game are actually pretty fun to fight against and function differently from one another. They force you to evaluate the situation and pick your targets. Very satisfied with that. The story is pretty cool, feels like one of those action movies like Beekeeper or Taken; you have to suspend a little disbelief but it's pretty badass. Your AI teammates will perform certain actions (opening doors, talking to you, giving you callouts) which allow you to appreciate the characters and increases immersion. Personally, my favorite part of the game was using the ballistic shield whenever it spawned. Probably the best implementation of the riot shield I've seen in a VR game. It feels good, holds well and feels really strong. I think my only serious gripe for the game is that the final boss is very underwhelming. Nikolai is just a reskinned Heavy Minigunner which didn't take too much effort to defeat, though the entire ending sequence was very cinematic which compensated for that. That and the gunplay is a little meh. The game doesn't have much replayability after you beat the campaign. The campaign is pretty short (it's about 12 missions, each mission takes about 15-20 minutes) and it doesn't take too long to beat. There is a Wave Shooter mode meant for multiple players, but the game is pretty dead so you probably won't find anyone to play with (hmu if you want to try). Closing thoughts: Loved the game. Wish the campaign was a little bit longer, but that's alright because it was fun anyway. If the game is on sale and you're seeking a fresh VR shooter experience, I recommend the game wholeheartedly.
A fun modern military shooter released in a time where there barely are any left aside from CoD, though I have the suspicion that the game was supposed to be a regular shooter or a rail shooter first befpre being converted into VR. First of all, the game wanted me to grab a controler when starting the game and all button prompts are shown as XBOX buttons as well. Secondly, compared to other VR games some other reloading mechanics, like putting shells into a shotgun or putting a new rocket into an RPG are automated. And third, enemies rarely press their advantage and a mostly static. Sometimes you have a few that move closer when you reload or are distracted by other enemies, but most of the time they keep standing at their spot taking potshots at you. Overall the game feels more like it was supposed to be a rail shooter. I don't mind that, but it is very linear. There is no exploration and even if you can explore a bit, there is nothing to discover. The game itself plays like your traditional Call of Duty campaign. You spawn in a level, are given some story elements why you are there and then shoot your way to the exit. It's also just shooting, there are no puzzles or anything else. And just like in CoD, you are limited to 3 weapons only. 1 main and 1 secondary weapon that are given to you by the game and can't be changed and 1 tertiary slot you can fill as you chose with the weapons you find in the levels. There technically is a 4th slot as well, given that you can still pick up guns as much as you want and can reload them as well. You just can't holster them, meaning they will disappear if you die. ( Oh, and once equipped you can't exchange your left shoulder weapon for an other one. Once you have chosen, you've chosen you soulbinded it to you) Speakin of, there is quite a good selection of guns as well. M9s, DEagles, FAMASs, M16s, Glock 18s, Miniguns, Grenade Launchers, Bolt Action sniper rifles, all the guns you expect from a shooter are here, with some being more rare than others. Ammo is infinite for your regular guns and while special weapons like the Minigun or RPG can run out of ammo, it automatically recharges over time. Same goes for your grenades and the healing pen you have (health is still regenerating). I do find the game a bit weird with the guns though. I assume it's realistic, but unlike Arizona Sunshine for example, you can eject magazines from psitols and SMGs with a button press, but for rifles you need to eject the magazine by hand. Yet with double barrel shotguns you eject the empty shells by a button press again while pump action shotguns require you to pump in the next shell manually. Pistols and SMGs also can be reloaded by holding them to your chest, but only pistols allow you to reset the slide with a button press. With SMGs you have to chamber the new bullet manually. And any other weapon type doesn't have the hold to chest to reload mechanic at all. I understand why they did it, since it makes dual wielding and using riot shields so much more convenient. But it feels inconsistent. As for the enemies, there is everything a modern day setting has to offer as well. Rifle troops, Shotgunners, Shields, snipers, LMG and Minigun units, RPG guys and Ogryns ;) What differentiates them from CoD is that they come in different tiers, with those in higher tiers having more health and dealing more damage. Overall enemies are somewhat bullet sponge-y, which is a nice plus for me. The campaign has 13 missions with each being around 20-30 minutes in length. You can also play it in 2 player coop. You can chose between 6 difficulties. Easy, Normal, Normal+, Hard and Too Hard and Realism, which is basically Hardcore (limited ammo, no HUD, both you and the enemy take increased damage). The whole campaign can also be played in 2 player Coop. There is also a 4 player Coop mode with 50 missions. I didn't play that myself yet, but at least it lets you select your own equipment. New guns have to be bought though with ingame currency. All in all Sierra Squad is a simple, but fun Arcade shooter that fills the hole modern military singleplayer experiences have left behind.
