infinity mode solo vs group ?

You're definitely gonna want a group with you. I could barely get past wave 10 on my own. I've been pretty successful in getting past wave 30 with one other person, but the more you have with you the easier it gets. 

If nearly done 25 but i died :D the trick is for the boss wave beat the boss till reinforcements and then ignore boss enough to focus on reinforcements, then force boss to spawn next reinforcement wave and finish that.

If you ignore gnome king to much he go to a point destabilize time so can't fully ignore him, but if you try destroy him you gonna deal with 2 reinforcement waves that will defiantly kill you.

Actually got 1 leg character sticker for corn for completing 24 waves or well nearly 25.

I get to about 35-40 every time on Solo, but usually quit (let myself die) after Wave 25 because I have enough Time Shards to earn an Infinite Infinity Chest (25,000).

Just try to avoid picking up Time Shards until you need them (I usually try to keep myself around 1,200 HP). Move around them when roaming the map. Every fifth wave, Time Shards will automatically be collected when vanquishing Gnomus, and you will be restored to full HP as well as full Time Stability after every Boss Wave.

psn id btw Zer0K3wL1337 just make sure to add note to why you add me like garden warfare 2 or infinity mode etc.
